Any of you guys ever put a 300rude v8 on a 16 footer?

[ratman67]

I have a fresh evinrude 300 but not much by way of a V hull around here in Colombia where I’m located. There is a 16 foot bow rider I can pick up cheap I was going to remove the upper section deck and interior and add full length stringers and a few addl layers of glass throughout the hull to rigid it up and add some weight. I will add a ballast box in the bow to counter balance that big ole V8. What else can I do to help it like that big heavy v8 guys? I was going to build my own setback bracket to raise up the engine as it’s a 25” mid. Thx in advance for any advice, rm

[ratman67]

Would adding long offshore tabs help it feel like a longer boat? Thx

Thx. That’s what I wanted to see. Due to this being a v hull the relationship of the powerhead height to the hull would be about the same as that tunnel due to my engine having a 25” mid. Thanks. I’m gonna have a go at it. Rm

[SS Minnow]

I am all for big power on little weight, but at some point it has great potential to get ugly. Be careful, have fun, and take lots of pictures and video to post here.

[Captaincj]

what do you recommend?

Honestly, a massive heavy V8 propped up on a tall 25" midsection attached to a small/short v-hull is a weight/balance/stability nightmare and recipe for disaster/injury.

Just my opinion.

[home made tunnel]

I can attest to not turning fast !!! I have a tall 20" motor on a little tunnel. Mine's only 13', and a 370lb four stroke 115hp. It can get squirley on the turns. FUN though! haha.

[mrichartz]

Was looking for pics first but still looking..
We redid a 15' glastron 30+-years ago transom,stringers,floor,deck etc to hang a 300 on but was 20"
And if floated and drove great in a straight line in glassy water but was useless for anything other than a straight line and even then took a set to drive wide open..I would think a waste of time and a good motor for that you can't find a better boat to put it on? I mean was totally useless for anything else..
no I didn't drive it we just did the glass work and paint.

I’m too busy to waste my time punking anyone.
Where I live 98% of the boats are flat bottom workboats or 14 or 18* hulls 30 to 45 ft long for carrying tourists to the various island in the area. There are zero 18-24 ft 24* hills anywhere and importing boats is almost impossible
I know where I can buy an old 2.5 merc 250 for cheap but have no idea what kind of hours it has on it or shape it’s in mechanically. I know it would still be a lot of motor for. 16 but with a 20mid and much less weight is seems way more doable. Not looking to kill myself just put something together that is a v bottom and will run hard when it’s not very choppy out, rm

I wouldn't do what you are proposing.

[ratman67]

My only other option is building a boat from scratch. I was thinking I could make a plug from plywood and cut the lifting strakes on my table saw. I worked as a bodyman so fairing it all in and blocking it true is just time consuming for me but I think I can pull it off. But doing all the glass work non stop to build the hull in one shot is what I’m concerned about. I was also thinking if I used the plywood plug and instead of pulling a mold from it to save time and money as it’s a one shot deal. Use the plywood as a mold to lay the glass on top of! if I sprayed a urethane paint on top of the plywood/body filler. Then applied a release agent, I would Build the hull, then use my air tools to cut the lifting strakes and hull edges etc square after its all dry. then pull the plug out of it invert it and then install the wood for the transom stringers with west system epoxy and then glass over all that on the interior with west systems epoxy. I’ve been talking with glassdave over on oso as to how to build a one off boat myself.

I know a 25” rude V8 300 isn’t the hot set up for this application but I have the engine... I don’t want to wait months for find a hull, importing one is not an option. I was thinking a merc 20” 2.5 is much lighter and shorter than my 300 rude so as to not have handling issues. I’m thinkingNot much weight diff between a 16 and 18! i cant see two feet of length making a huge diff either. I have a 18 hondo jet boat with a 600hp bbc and that engine drive set up weighed twice as much as a merc v6..... my buddy has a donzi sweet 16 with a 383 and bravo in it. if the boat handles horribly, I will pull the 2.5 merc engine and stick a suzuki 60hp 4t on it and use it for water skiing and wakeboarding for my island resort. colombia boat building is 30 or 40 years behind the USA lol.

One question no one has answered is will long thin offshore tabs make the hull act like it is longer than it is and help stabilize it fore and aft? Thanks for any feedback. Rm

[magnum2.5]

Man your all over the place...what is the final goal?? the 25" v/8 is a beast to start with, and without serious work will not run as good as the 2.5 merc...besides the fuel issue...better get a good nights sleep....make a better plan...good luck

If I could just buy a 21ft superboat and hang my 300 rude on it and I would be done, the merc is there I have no idea what kind of shape it’s in mechanically or its history. Just told it’s a running engine, where as I know the 300 rude has 40-50 hours on it.
i think I will try hanging the 2.5 on the 16 and see how it runs. If it’s really a handful no biggie as I can still use the boat for water sports for my hotel. I could buy a new 21 but they are so expensive plus the freight. . and importing a used boat is impossible. That’s why I’ve given thought to building one. What I really want is a 21ft boat that will seat 5 and run mid 80s with a 300 on it. I live on an island that fast boats around here run 30mph. So it takes for ever to get anywhere. You fall asleep on the tourist boats at 30mph.

It’s not all that hard or slow to ship big things nowadays. I think you should find a hull you like, perhaps an HST? And ship it to you. I’ve shipped cars over seas it’s not that hard or expensive relatively speaking.

In colombia I cannot tag or title used cars boats or motorcycles period. New stuff is 60% duty plus the ride.

I lived in Costa Rica for 6 years there I could import anything I wanted just pay the freight which was cheap compared to South America rates, and 13% sales tax.

I am importing a couple of generators now and a large desal system I’m paying insane amount to get it into the country as lots of palms need to be greased but none of this stuff needs title or tags. That’s the real issue.

I even considered shipping a boat to panama and buy one with a merc 2.5 (I can use the parts of it as spares for the one I’m buying) and ride it to colombia and buy an old pos boat the same length and cut it up and use the hull reg number and docs for what I bring down. But not sure what bs I will run into in Panama.

Unless I have it unloaded into the ocean and ride it into panama for fuel supplies etc before heading to colombia which I’m told is about a 4 hour ride from Panama City to Cartagena,

on the other hand I have 7 carpenters working for me building new rooms and furniture etc at my hotel. In a couple months I might get a pair to help me build a wooden plug to lay a hull on. If that’s even Feasible, if not by using the plug to make a mold for a one hull build, the glass work doesn’t scare me and I could probably hire a couple guys to help me lay the glass if I decide to go that route. I think I will have a go the the 16 footer first tho, unless another boat comes up for sale, Rm.

[LakeFever]

Wow that’s intense regulation. I don’t know the South American market at all but I had no idea things were so difficult to acquire there. Makes me wonder why? Seems counter productive to me.

Sounds like the build your your own might be the way to go.

[baja200merk]

A 300 will work fine on a 16ft as long as you rhino line the Gearcase to break the surface tension. :leaving:

[MattGreen]

If you have 7 carpenters by far the best way for your situation is to build a wood-epoxy plywood boat from scratch. There’s a variety of boats by Glen-L, including (if I remember correctly - it’s been over 20 years), an 18 foot V-bottom sport boat ((Rampage ? Renegade ?) that is probably just about right for what you want. You could probably stretch it a couple feet fairly easily, and add a pad for more lift. Your idea to build a full/partial mould to build a Fiberglass boat is a hell of a lot of work for one hull. And working with polyester resin in your climate is not fun and has some technical challenges. There are epoxies tailored to your temperature that are essentially idiot-proof to mix. A properly built wood epoxy boat should last you many many years if rigged and maintained correctly (I owned mine for 15 years, sold it still in great shape). If you find a “stitch and glue” model you like you may even have a boat in a couple weeks - they go together really fast !

the boat building industry here is 40 or 50 years behind the states. No stringers in boats made here! Vacuum bagging lmao. I can only find glass mat or woven roving glass no bi axial or triaxial and. Or even regular fine weave glass cloth. Only polyester resin with a weird hardener you need to use a ton of.

The regulations on importation are the only reason the local boat building companies can sell the junk they build. Really horrific quality. Stress crack everywhere. Most places don’t have all the grinders, Sanders, etc to do quality work. Let alone the quality materials smh

[blacktruck]

What about finding an appropriate motor for the boat? Or if you or a friend are a "foreign diplomat" you can import to Colombia duty free. The Wood kit boat idea sounds fun too.

no one wants to do any diplomatic stuff as a lot of people got in legal trouble doing it for the narcos.. that ship has sailed! My partner and his daily are pretty well connected and they couldn’t help a buddy of mine get his Escalade tagged here in Colombia

I’m on scream and fly not putt around in the bathtub.com. Lol. My street bike is 180jp my súper moto 63 hp both my blown 48 anglia and pro touring 67 camaro have over 800hp and you want to be the voice of reason lol. I just don’t see myself in a 16 ft bow rider with a 115 bro.
I would really like a challenger or a splash of it if I could to hang my 300 v8 on I’d even find a 20 mid for it. But I doubt there is one In The country or even a splash. If I had more free time I’d fly to panama and tried to see what is involved with shipping a boat there and driving it to colombia. I can get away with buying an old boat the same footage and swapping numbers I think. That Might be what I end up doing. In the mean time I’m going to pick up the sixteen and see how it sits with 550 lbs on the transom and go from there... if it looks scary I will try something else
I was also thinking of maybe cutting the 16 up and stretching it to use as a plug to pull a mold off of it. Next time I go to Cartagena I will have a good look around. There really isn’t boat trader or eBay here yet. They have a site similar to eBay but very few pleasure and even less performance boats here period.

Thanks for food for thought. looked at the renegade and it really didn’t do it for me. Nothing cheap about building one with all the hardwoods that are needed and I still would not have what I want. Who else build wood boats for offshore with a 22 or 24 degree hull? I would think they would all be onboard powered with propshafts and struts tho from that era.

While I know its generally frowned upon to suggest people pursue knowingly risky approaches with engines/hulls/lowers here for GOOD REASON too it does seem as if you have little option and if you hang it off that 16' obviously your going to want to ease into things slowly finding the limits and whatnot. I know two guys who bolted a vicious sbc into a 14' and sunk it first time out. Both lived but the boat didnt.
