Hello, I just got a 15' G-W and have a few questions!!!

What motor is a good choice for this boat?
I've talked to a few of my friends who have boats and have gotten a wide range of ideas, everything from 70hp-140hp.
What are you guys's thoughts?

Also is there anything tricks with these boats I should be aware of?
Like set backs, steering options, fuel tank placement, things of that nature!

I'm very new to boats, and would like to hear from people who have owned these!

I have a few friends who are extremely good with boats willing to help me with this, and they said to find people on here who have experience with these boats for tips & tricks!!!

Thanks
Bruno

Please post some pics!!! These boats are not very common in that length. Check out the one I am restoring in my signature. I will be powering it with the 1969 merc 1250 (125 hp) That it originally came with, it used to run in the low-mid 50's with a long shaft and no jack plate. I have since mounted the power head to a 15" mid and will be using a jack plate in the future, and turning a chopper of size yet to be determined. Welcome to Scream and Fly, you will find everything and more that you ever wanted to know about boats, old and new.

It is very rough, but a friend of mine gave it to me. He figured I'd have fun redoing it, then running it!

I have never really done anything with boats(always wanted to) I've always done cars & bikes!
So this is veery new to me!

[xtremeboater]

that will be a cool little ride

I have a 1970 G.W. Invader looks similar to gw1250's but my cap is different.

I run a 1974 J block 150 with 4 inches of set back and up a tad ( gotta keep some secrets ;) ) last year it ran better than 77 on GPS. Keep weight low and to the back as much as you can. Laker on here has a buddy running one with a 140 OMC that runs real good too, might want to pick his brain.

Thanks for the compliment Matt :thumbsup:

[BRUNO44052]

Thanks guys!

A friend of mine recomended a 85hp V-4, would that be too underpowered? My other friend said a 140hp X-flow?

And are these boats able to run with two bench seats (say 4 people two being kids)?

I think that is what Laker's buddy is running. I say put a Merc inline 6 on her and let her rip :thumbsup:

It would not be under powered for pleasure & skiing, but you'd never see 60 mph

2+2 should be fine, esp with 2 of them small

[specboatops]

your is exactly like mine, I also straightened and sharpened the last 3 feet of mine. They are very fun boats and draw a lot of attention when out running.

[gw1250]

I need to finish my project and we need to talk!!!

Chris

[BRUNO44052]

So you guys recomend either a 140 V4, or 135-150 merc?

I appreciate all the help guys!!!!

[specboatops]

I need to finish my project and we need to talk!!!

You need to finish your project and we need to hook up and run these bad boy's ! :thumbsup:

[k-man]

looks just like the one my dad picked up - gold metalflake - that transom was something else , we also raised it 4 "s @ its the one u guys are talkn about - with my old x-flow 140 great fun boat - it has dual ride guide steering - land & sea soild mounts & nose cone - cmc hyd jack - block is stock other than i rebuilt it a few years ago .020 over - he's turning a omc 27 soild hub race cleaver about 6500 rpm if ya push him - lol - but he doesnt like turning it over 6 - i think he's thinking of selling it - transom could use some glass work but still solid - gotta love the sound of that thing when he cracks it open :cheers: - id like to see a 175 fast strike or intruder on it - but that 140 rocks pretty good

[delawarerick]

A light weight option would be a 3 cyclinder omc. Wingnut had one that pushed some hp and was light. Rick

Definitely, that would turn some heads. :eek:

I was hoping to get up that way some time and run with you and Scott.........I hope you don't get rid of it...............these old boats are hard to find...........

jeff janaky owns it now - bought it from my dad lol - was hopen to see u guys run together myself :thumbsup: - and yes he fiberglassed that thing in our basement - stunk up the whole house more than once - carried it out the patio doors :eek::eek: - its an adrenile rush 4 sure - a deffinantly turns some heads & pissed off more than a few 6'S with the 85 cover - most of them said when i heard it open up , i knew i was screwed - gotta remmeber this thing has been around 4 awhile - good luck with your project but be safe & do it right - the old man stuck a few bucks into it with good parts - i remember some of the 1st few runs with the ass end shimmying about a foot or so it seemed with a 24 raker at about 6400 r's - keep us posted

[Li'l Toy]

but I think Bruno is new to this---Looks like the hull was built with a transom for a 15" motor (yah, back then, 20" was a long shaft). Assuming it will have a 20" on it now, needs a serious and seriously strong transom buildup.

By the way, Bruno, looks like the new post worked.

[BRUNO44052]

Yes it did, thanks for the advice!

Yeah we are gonna redo the transom, so I can use a 20" shaft.
What's a good height? I was thinking of running a 4-6" jack plate on it, is that a good idea?

YO~ BRO, DAH GOOD OLD DAYS! JEFF'S RUNS WITH A HYDRAULIC JACK PLATE. MOTOR UP= DOWN WITH A TOUCH OF A BUTTON WORKS WELL. http://forums.screamandfly.com/forums/%5BIMG%5Dhttp://i693.photobucket.com/albums/vv291/HSPHYDRO64/DSCF0001.jpg%5B/IMG%5D

I have a post going on in the fiberglass section on this site, and put up new pics if you guys want to check it out.

[dusie454]

I have a 15 foot GW Invader completely restored with a 115 merc straight 6 5 inch setback center stear very fast nobody will ride with me

[tlinke2002@yahoo.com]

I've rode in dusies GW Invader. It was one wild ride!!! He's going to have to find a new rider, once is enough for me!

Any pics?

[KG4]

Here are some pics of Dusies invader.He is my dad,I posted these here before but i will post them again.

[KG4]

A few more:thumbsup:You should have seen it when we got it home,It had no bottom in it:eek:

[gw1250]

Thanks for posting those pics, my boat is a 4-seater and slightly different than the ones discussed on this thread, I'd like to have one of each some day. What kind of speed do you guys see out of that boat?

[Dave S]

There was one on the side of a shead down here and I tryed to get it but they was going to use it as a ducking boat.:eek: I hope they didn't cut it up. Ralph from lindinhurst used to have one with a V6 rude 30 years ago.........His first speed boat.:cool:

[specboatops]

Was just lookingthrew some old threads and wanted to get this back near the top. Love the Invader !!

Chris

[gofast26]

I have the chance to pick up one in decent condition from a buddy hull is in decent shape and comes with a trailer. Any idea on the value of a solid hull and decent trailer?

[Mark75H]

Value depends on condition, location and time of year. After frost, away from big water ... give away

Hamilton Bermuda or Iowa?

[gofast26]

He wants seven fifty boat is pretty much empty besides the wheel and seats. Theres a bench facing the motor and two buckets up front. Id really like to get this boat for around $500 but hes not really moving his price even as the snow approaches. And im in canada

That's a 14 footer not 15.

Lookd good buy it.

Chris

[gofast26]

How can you tell between that two so easily without measurements? Ive looked at pictures of both and cant really tell the difference. Pictures were in a sales brochure so it wasnt a very good visual source.

[gw1250]

Check out the pics of my resto in the link in my signature, that is a "15" ft invader. It's actually 15'7".

[specboatops]

By the seating configuration. The 14 had front buckets with a back bench, the 15 ( which is actually 15'1 " ) had back to back buckets.

Grew up near a Marina that was a dealer of the Invader ( Rever's Marina) Rockford. Ill.

[bearclaw]

Here's a brochure, not sure what year. I knew guys who had two different models back in the late '60's to mid-'70's. I started to post something I thought I remembered, but I had it hosed up; the 15 in the brochure looks like spec's boat. Has a lifting hull and more depth. I knew a guy who raced one in a small dragboat circuit back then in the area (OH) with a Merc 1100 and did quite well. The 14 in the brochure is very different, almost like a stretch version of the 10'. Very flat, spanked the water, I always knew when he passed our cottage, didn't even have to look.

[j90]

That is a 14 and what was said about the seating is correct. I purchased a 14 not nearly that condition with a 50hp and trailer for 450.00, same seating. I also have a 15 and the 15 came with back to back seats at least in 1972. as the I have also seen single seat 15's that were race boats when I was a kid. The 14 is about i1inch narrower.

I had heard that it was narrower but never new for sure. Thanks for that info !!

[Kathleen Michelle]

these must be some really fun boats it seems that way with all the pics. you all have posted and especially with specboatops video.

[hoganmj]

I have been researching these boats for some time. A friend of mine had one more years ago then I care to admit, and I remember that he used to reconfigure the seating at will. The bench in the front, and the two buckets in the back or vice versa. So I'm not convinced that the seating configuration is the key. I was under the impression that that it was the gunwale configuration. Take a look at the two enclosed pictures. The blue 14' has the open gunwale. The green 15' has the closed gunwale. Am I wrong?

[99fxst99]

A friend had one in "72-73 with a 15" 50 Johnson looper. Ran low 50s with a 2 blade 23" OMC aluminum prop (best we could do). A blast in a straight line, but would beat the salt off a cracker if you hit any waves at speed. Wouldn't turn around in a 10 acre field. We slid it up on the beach once! All in all, it's a wonder no one got hurt in it, but we didn't know any better!
I always thought the v-bottom GW looked suspiciously like and Allison........

[Chips overboard]

Hi , does anyone know what this is? I found it glued to the upper deck behind the steering helm of my 14 ft Gw invader . It is hardly legible436766 but if someone else has one maybe it can be read. My title says it's a 1972 but I think it's a little older.I took a photo so you can blow it up and maybe help me with this I.D. This boat has no Balsa core and feels pretty lite. It has original transom thats mint. No other no#s anywhere in the boat, just this paper under some resin . Afraid to touch it for fear of it disintegrating

[specboatops]

Who??

Looks like a build sheet. Specs colors & rigging & options for the assembly line. Couldn't make out any of the info in the blanks.....specs out layup also.

After looking again , not sure there is any info written on it.
