A huge downside to an outboard is that they generate very little electrical power because they have a magneto. This is compared to an inboard engine, which have a full sized alternator.

If you plan on having any house load at all, and a 26 foot boat is going to have a decent sized house load, then you want an inboard.

Re: Outboard Or Inboard

The cheap alternative if you are happy with 6 - 8 knots would be to put a 30 - 50hp outboard on the stern. Then you are looking at 3-5 gallons an hour.

Re: Outboard Or Inboard

Yeah I think your right I'm best of putting an inboard engine in, thanks for your help.

David, I think for a planning hull it will need 150hp plus, so will have electronic ignition and 40+ amp hour charging capacity. Even a smaller 30-50 hp outboard will generate enough for lights, radio and fishfinder etc.

The alternative is a small diesel but the cost and time to install would take a long time to re-coup hence the suggestion of an outboard which would solve the steering problem too.

Re: Outboard Or Inboard

I recommend the "sawzall and dumpster" propulsion method for that hull.

David M - are you trolling?

Re: Outboard Or Inboard

Aloha and welcome aboard!
I'd get a diesel inboard for your boat. Get the most popular engine that has the easiest and cheapest to find parts. I don't know if you have access to the older Perkins but I really liked the one I had in my sailboat many years ago.

Re: Outboard Or Inboard

2 cents mode -

That boat is meant to be a "speed" boat. If you don't get 100-150hp on the boat it will be unsellable in the future. Or it will have to be a giveaway.

99% of people looking for a speed boat will expect it to go fast.

I don't think that transom is setup or strong enough to hang an outboard of that weight and size.

- Option 1 - 4 banger gas and v-drive
- Option 2 - Rebuild/strengthen the transom and 100-150hp outboard
- Option 3 - Some diesel solution that pushes the boat like a trawler

The easiest is option 2. The most desirable is Option 1.

oh... Option 4. Sink it it and buy a sailboat
