Sorry guys, I could have stated that more clearly. I should have said that its the boat builder that can round up, not the end user. Good catch.

peter8 Troy, If I'm reading you correct and my numbers are 18'x 6.33 x .8 - 25 = 66.15 . I can round that up to 70hp and be legal ? No matter if the Lund plate says 55hp. My reason for the legality is a very by the book local warden where I keep the boat. My other option is a decal job, but if the C.G. formula is correct I'm good w/ my 60hp . Thanks

Troy LaTour The part that was not in the Ranger post was what the actual rating should be. It is stated like this: if your numbers are correct, being it comes out 66, you can round up to the next multiple of 5. So, it would be 70 HP. Thats what most boat builders will do. There are so case though where for many reasons a builder would rate the boat down. we have done it both ways for different reason. Now, if your numbers had come out to be lets say 61.24, you could round it up to 65 HP.

C.G. hp rating

If I use the formula from the Ranger post : L x W x .8 - 25 = hp rating for a tiller boat I end up with 66.15 for my old 18' 1968 lund SSV. I've also been told that you can be within 10% of the C.G. tag. Both options mean the 60hp I installed fit within limits (tag says 55hp). I don't care about insurance issues just legal ones. Does anyone know for sure what the law is ? I do know that the boat handles the motor just fine. This subject has been discussed many times but I've never seen the legal answer. Thanks for any help.
