My V-20 performance

[chrisrub]

I have to be honest I don't know much about props. The one that is on there came on the engine when my grandfather bought the boat from the original owner. It has never been replaced or worked on as far he and I know.

There should be a number on it someplace, either on the prop or in the center were the nut is, find that and go from there

[cterrebonne]

yep right behind the nut and washer, you probabaly could see it without removing those items. it will say somthing to the effect of this 13 7/8 x 17 the last to digits are your pitch.

15 pitch stainless will be your best bet for that boat. You have the same basic combo as my V and I topped out close to 30, and cruised around 20-22 turning 4200-4400 RPM's. My max RPM's were 5300. Milage on that boat is actually not very good as it is underpowered pretty badly. That 115 is working it's tail off to push that boat. Mine burned 32 gallons in just over 2 hours of running, so 1.5 miles to the gallon is about all it will get. Unfortunately your best option is to repower as there isn't alot you can do to that 1.6L to make alot more HP. You could swap over to a bubble back exhaust and go to the bigger carbs, but it still would only get you a few more HP and use ALOT more fuel. At least you already have the right boat to start a bracket project with. Where are you located at?

[chrisrub]

I'm located on Long Island, NY.

I figured the answer would be that it is severely underpowered. It just doesn't seem like enough HP to push the boat and be fuel efficient.

I've thought about getting a bracket and starting a project, but that may be down the road a little bit for me..

Thanks for the replies

If the SEA-DRIVE portion is still good, you could swap out a larger OMC onto the SEA-DRIVE assembly. This isn't an easy option as most of the time the bolts are coroded into place to the point there is no hope of getting them out. If you could though, you could swap a 200 or 225 over to your assembly. Although you would probably need to beef the transom a bit as a 225 SEA-DRIVE assembly is HEAVY!

Ferm, what about the 140 Seadrive, could you swap a V4 looper on to the existing bracket?
