Gots a question for you OMC gurus??

[Swamp boy]

Aight I've been doin some thinkin. I'm very interested in performance boatin in every aspect and would love to play with every kind of boat as well as every motor setup I could. Maybe one day that'll happen.:D

Anyways I'm not a big Merc/OMC guy. I love both of em. Dads always run OMC and I've run Mercs. Boat currently setup with Merc 15" 260. Aint nothin wrong with this but I'm thinkin about tryin a OMC for a lil while just to play a lil with.

Motor is a 20" 88' 200xp (Believe thats a looper, not up to my OMC terminology:o) with no lwp. Motor is basically stock at the moment. Would like to put it on a short mid and get LWP on the the lower. What would I be lookin at $$$$ wise for that and where's the best place to get it done? Also doesn't Spanky or someone have a conversion for the Merc to OMC controls so nothin in the boat would have to be changed?

Would this motor be a good one to test with? For the time bein it'll just be bolted on and ran. I'll paint motor to match boat but will not be moddin to much at 1st, only as money comes up. Just would have to have a short mid and low water for the time bein. Then lieght wieght flywheel, more compression, etc..... to start doin some testin to put down on paper.

All this is just in fun, I'm just wantin to try something a lil different. (Not to mention I dont believe there is a white motor on our river thats mounted on a performance boat;)). If ya have any suggestions, comments, know of something that would be better, or just think I'd be crazy to fool with it feel free to let me know you .02.:cheers:

Thanks for any help!

Yep, it's a Looper. You can get the mid cut or get one from Taylor, and they can cut the drive shaft too. Or, I've got a nice 12" mid for sale:D I'd send the lower to Titus.

You are not going to get the same kind of numbers you would with the Merc with a stock Looper. Stock limiter is 6700. I'd do compression and get rid of the limiter first, then carbs. Get used to running a bigger prop, and all of your Merc props will work too. It would be neat to see you set a baseline then document the gains of each change as you do it.

[Swamp boy]

HMMM.... a 12" ya say?:eek:

Would like to right down the changes after each mod and see it on paper. Right now its bone stock and never been run on anything but a fishin boat. Dad picked this one up last year for I believe $750 complete top to bottom is very great shape. WTF???? You'll pay at $6500 for a complete Merc.:nonod:

One major problem is I'm the only guy around here that I know of that would be runnin one espically as a hi-po application. Looks like I better get used to I-10 goin to Sam's if I do decide to swap over.

I have approx
lwp mod approx $300
mid section approx $2000. , thanks to Wayne Taylor
donor motor complete $400.
and it is a very reliable motor still stock compression so 87-89 octane and I can bang right at 100 gps, it will take a lot of work to even get it close to a stock merc but it is fun to be a little different some times, Matt:thumbsup:

Taylor Marine is does make the mid you're looking for but have been told its a little on the heavy side can also it for the Merc LU, which seems to be the way most go. There used to be a couple that cut them down but not sure if that's still the case but heard some of those would crack after doing it. Racer has been in this business a long time and he might have the best answers for you.

For the power head, no way your going to be happy with a stock unit if you've been running a Merc 260. You're looking at 60+ pounds more weight on a higher center of cravity and a lot less hp. Now, in the right hands, that old fishing motor could really put a smile on your face, but it ain't gonna be cheap. Old saying goes, "ya wanna play, ya gotta pay".

[jphii]

I think that a Merc lower is a waste of money. The guys that can't keep an OMC lower together are doing something wrong. I've NEVER had a problem with either of my Spanky lowers. All I do is put in a new water pump at the beginning of the season and fresh oil. I know a guy that does the mids, and he cuts it to 15", not 16".

[Swamp boy]

I've got a 15" sporty now and a 15" 200 case. Have 2 20" OMC cases (well 3 countin the one on the GT150) that could have cones put on em. :thumbsup:

Whats a OMC worth ( not sure of the powerhead year/model yet) but has a short mid, lower but needs pistons worth? If I could find a good deal might just pick up a complete deal.

Damn ya'll got my lil brain smokin thinkin about all the possibilities, combos, etc .:cheers:

Yea right... and how many miles do you run at one time? :rolleyes:

I know a bunch that will disagree with that.

And the reason to cut to 16" is to keep the trim pads.

I surfaced my omc lower for the last 6yrs full of water:eek: with one 1/4-20 pinning the carrier.. its been on 4 boats, its got some miles on it. All i did to it was change the water in it every now and then:D

he hasnt caught me yet :eek:

[jphii]

I hear ya kid. I've been known to put a few miles on mine too:rolleyes: And we probably beat the piss out of them more than most people do.

:iagree: im gonna be on tarpon tomorrow testing it with the new seals in it and actual oil in it for once:eek:... this is my first spanky lower, it was over 100 the first time it saw the water :D dont tell him:leaving:

phill ya planin on comin down for RR or anything??

kid

[STV_Keith]

If you have the lower already, just buy another driveshaft and get an adapter. Use your Merc lower on the OMC. :) Personally, I'd say go with a V8 - if you really want the power, and the "holy ****" factor, get the V8. LOL

I will be putting a monster Monty V8 on my STV as soon as I can afford it. Phuck it, you only live once.

We may be adding a few more races so it's going to be a busy year. Might make Crooked Lake if I can swing it. We're having a big event at Bucksport in March. You guys need to come up for it.

[QUOTE=jphii;1569884]Get used to running a bigger prop, and all of your Merc props will work too. [QUOTE]


Your merc props will work if you want to drill out the front half of the splines.
If you are running a flo-torque hub, then you just need a new OMC insert.

I have read that pinning the carrier is the key to the OMC lower. My personal experience with the OMC lower was a crack right down the side of the case, right in the middle of the bullet. That's why I went to a merc lower. If you are going to cut down a mid, and have a driveshaft cut down also, might think about converting to a Merc lower while your at it. Just food for thought.

[baja200merk]

the only reason id swap to a merc lower is for a 1.62 ratio... i think hes got a whole bunch more chit to figure out b4 he worries about cuttin the lower. Hey david wit the grey motor your half way to right :D

OK. Sounds to me like he needs to do it first to get it on the boat. But I guess I misread that.

Kev I like the grey motor too:smiletest:. Love that setup and look as it is. Gonna set the boat up, playin with props, lowers, etc for a couple 800' races. Gonna keep this motor and put on a stand sometime after that. Got to rebuild my 200 merc and prob sell it to fund a OMC shorty mid.

Gonna stick with all OMC when I do convert. Will make the trip down to Jacksonville and let Sam work some majic to make it run like it can. Not gonna make a drag motor out of anything (unless Sam just feels like hookin a brother up:D) just a river ride motor that looks a lil different then others around.

As far as color and bein photogenic I'm thinkin lite wieght cowl in prob red with black decals, white shorty mid, and black coned lower. Should be fun to play with.

Once I get caught up here and get time away from work and school I'll get started. Kev, you and Sam will have to take a look inside this thing and see whats gonna work and what relatively inexpensive mods can be done to make it run right. I dont have anywhere near the knowledge on these things ya'll and the other guys do with em so it'll be a great learnin experience. Plus messin with the OMC stuff might give pops a lil spark to get more interested with the performance stuff.:cheers:

Gots to go check the serial number this week and make sure of the year of Looper since the 87 is a 2.7 and 88 is a 3.0 I believe what Sam said:confused: so I'll know what parts and pieces to look for.

Taylor Marine is the best place to get a short mid??? Or can somebody cut one thats just as good, as well as the drive shaft for lower??? What kind of $$$$ we lookin at for that (mid and cut shafts)????

Tryin to start gettin some figures on paper to see what all I'll need and money to fund everything.

Thanks for everyones input so far.:thumbsup:

Man i hope i have as good as luck as you do with this OMC lower on my V8 on the surface.

[lokinutz]

So, you guys who have shortened the OMC shafts, how are you doing it with the taper on the end of the motor-end of the driveshaft? Are you cutting them and re-welding? The Mercs run a thicker diameter driveshaft the full length, so all you have to do is chop it off and cut the splines. No cut and weld necessary. Just curious how is the best way to do an OMC.

serial numba :confused: nex time u talk to spank tell him the kid said the serial # is Whi-t/e~p0w@... when that doesnt show up in the OMC book my phones gonna light up :reddevil:

taylor mids are the "mac daddy" mid for a OMC, no doubt... but for a run around motor with a "stock" (you noticed the quotes right?) mid it will make the power. with that being said, a cut down would be last on my list. say what you want :rolleyes: a short mid aint gonna make or break a race.... sell the gray motor, invest half of it in a 3.? "SLOMC" and well.... u get it...

my biggest problem with my spanky motors is they dont run real well after you stuff the LWPU with weeds and get it up over 260*.... :leaving::o:o:o:o but other then that all ya gotta do is beat it like a circus animal :thumbsup: its surprisingly easy to do :leaving: {i have plenty of instructional video if you need it} :D

OMCs go by model number.

Taylor is the only place that makes a single casting mid that I know of. You may as well get the twins to cut and set up your swivel/tilt bracket. Even then you have to do some grinding for clearance to get it to tuck in all the way. They can also respline the merc drive shaft to OMC splines if you go that way. If you stick with the OMC you'll have to have it cut and welded. I would say at the least pin it. I have on that is pinned and sleeved because of the carrier wallowing in the housing.

[jphii]

Look at the ignition. 2 packs, 2.7. 1 pack, 3.0. You can also get short single casting mids from Sea Way. If you go with Taylor do like F/C said. Send them all the parts and get it back turnkey.

somthin like that:rolleyes::rolleyes::rolleyes:

[BarryStrawn]

For the Johnson/Evinrude lower with two piece shafts, you can cut off the bottom and respline the driveshaft from a 25" model.
