Tunnel hull for 15hp

[davidkyle323]

The longer the boat the less it will sink into the water when not on plane, but the longer the boat the more drag created when on plane for top speed. Tunnels usually work better the longer they are but never had experience with one with that low of HP. I have had them with 25hp and I now have a southfork with a 40. My old tunnel was a 14 foot and it drafted a lot more water than my 16 I have now. But it was also a heavy made boat.

Thanks for the advice, David.

I'm wondering if a 25hp would be a better choice. I was gonna get a 15hp since you can pick them up by pushing down on the tiller handle for jumping logs and shoals, but if it won't push the boat I might need to get a 25hp instead?

That makes more sense! Would go with 18x42 with a 25 3 cylinder yamaha, those wide open reservoirs can get ruff and a 36 would be dangerous. A 40 would be tits and shouldnt be that big of a $ difference.
