Hi there, I have a 17 ft dory hull cabin boat, I am only going to be going 1 - 3 miles offshore max. Would a 15 hp be okay for this boat, im not one for real speed,
Thanks

Not too sure if a 15 would get it on the plane and unless you do get on the plane your fuel consumption would be high. I would suggest anything between 25 to 40hp.
Cheers

Hi John,
you could also find yourself with just enough power to hold against tide, which could mean you could even find youself full power foward and still going backwards in the wrong tidal run. For example, on Monday we were out and the tidal run where we were was such to hold still at our mark the boat was pushing 7-8 knots. I would agree with Rabbi, and get something with a bit more grunt. 15hp would do you as an aux engine tho.

But hey, I am no expert.

you would be wise to get something between 40 and 50hp or even find out what company built the boat and see if there still in existance because if they are they will give you all the info you need

I agree with ED I have a Quicksilver (17ft 10in)with a 15 hp aux and it will shift it but not very fast if you are going 3 miles offshore the weather can get up in literally minutes.

I would go for at least a 50 for main engine and keep the 15 for aux.

My main is a 75 hp with that I can get 30 + knts on the plane.
