I want to put a 70 - 90 hp, 4 cycle engine on my 68 Nauset.

I'd prefer to go with a 90 hp, but I see they are very heavy. Any problems putting a 400# engine on my 500# hull?

Some folks have put the 400+# engines on 16/17 hulls, Mark. My opinion is that is too much weight.

Many of us have the Suzuki/Johnson/Evinrude EFI 70hp 4 strokes (336 to 356#) on 16/17 hulls and are quite happy with them.

Mercury's EFI 60hp 4 stroke is another option, and quite a bit lighter.

As good as they are, I wouldn't get a carbed 4 stroke in a power range that offers EFI. The computer just makes too much difference.

Good luck.

I saw a new Honda 90 on a 60's model smirkless hull the other day. We were actually running together during the island cleanup. It could've smoked my new 170 at any time. Neat setup I thought. Jim

I second the Suzuki/Johnson 70hp for a 17'. The old blues are much lighter than my Newtauk so performance will be great. I get 38+ with my 70 and only burn 2-2.5gph at 25mph.
