My V-20 performance

[THEFERMANATOR]

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?

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?

Alright I did a little math (with some help).....1.6 litres comes out to 96 cubic inches. With my limited knowledge on HP vs. CI, I'm thinking that the max HP that you could or would want to get out of a 1.6 litre would be about 115hp....yall agree with that theory?
That being said, would Wellcraft hang a ~115hp motor on a V? I thought they came from the factory with 150's or 200's????

The 1.6L SEA-DRIVE was a factory option, I have one sitting outside. Yes it was only a 115HP flywheel rated engine, roughly equivelant to a 100HP engine today as we now rate at the prop. You could find a 140 SEA-DRIVE assembly as they do pop-up from time to time and swap it over to it. Or you could find a 25" shafted 150 or 175 cross-flow(there a bit thirsty still, but light weight compared to a looper) and take it loose from it's mounts and swap the powerhead, mid and lower as an assembly over to your SEA-DRIVE set-up.

Since you're in the great white north, that most likely means your boating season is coming to an end right now. I would sit back and watch craigslist and ebay for a used bracket and a used outboard. With the way things are going right now you could find a bracket and outboard in good condition for under $2K and just re-power it. Also watch that SEA-DRIVE assembly. If something breaks on it you would be money ahead to re-power it. Parts for the SEA-DRIVES are almost impossible to find when you need them, cost an arm and a leg, and will most likely not be in much better condition than your broken parts. You have to remember that the newest of the SEA-DRIVES out there areabout 20 years old. And these things were put on boats that were meant to be run in saltwater. They are getting all used up for the most part unfortunately, and OMC has long since left the scene with any new parts.

Thats interesting stuff to know that Wellcraft had a power option of a 100hp motor. Here I am worried that when I hang my 150hp on mine that I'm gonna be lacking in power. I know alot of guys on here run 150's but I still have that worry.

I have the 2.0 model sea drive and i hit 55 mph w/ 225hp via GPS in 1-2 foot seas. Its gotta be the prop. go to the prop shop and get a new higher p prop or buy my seadrive and motor and slap it on there and hold on, ill take 1500.00 for the whole drive and motor and its already off the boat, i had a bad transom.

I will definitely keep that in mind if I decide to go that route. Right now I am looking at some other boats, but still haven't decided totally against a repower. Thanks for the offer!
