[digimortal777]

hi<br /><br />i have a 18 ft fiberglass lake boat / rowboat <br /><br />i want to put fins on the stern to lift it out of the water when going full throttle , i baught a dole fin but it dosent help much because of the shape of the boat<br /><br />there is 2 boyency tanks under the back seat which are part of the stern too<br /><br />if i want to put on fins like everyone else does , could i use self tapping screws and silocoe sealent to do it, i need to get exra lift my 9.5 johnson is a low profile model and bcause of the shape of the shaft it catches a lot of water and sumtimes i get splashes coming in over the transom<br /><br />ill be upgrading to a newer 15hp next year and the fins would help an awful lot for that as ill be getting a 4 stroke which will be heavey too<br /><br />i am about 220lbs myself so thats a good bit of weight when i go out on my own<br /><br />any help appreciated

I guess I dont understand what you are calling boyancy tanks. Are you talking about the part under the seat with foam?

i really don't think much will help.. your just way under powered.. if doelfins didn't help ,,addin' real hull type fins wont help much .. it'll just make it bogg down.. <br /><br />see,, you can't get a 'change-in-effect' for free.. it's gotta take away from somethin' ,,i.e.,,power..<br /><br />but say you do anyway.. self tapper srcews into what ..??? fiberglass an what..??<br />maybe some wood backin'... maybe not... or what..?? into the boyency tanks..?? what are they ..?? aluminium..?? or whatever,, can't be very thick for a good srcew hold whatever it is... <br /><br />bottom line.. nuthin' gonna help but a larger motor..

http://www.pike-ireland.com/boats.html <br /><br />if you go to that URL anc click on the first thumbnail pic , you will see the type of boat i have , only mine has wooden gunnels and seats , but the hull is pretty much the same , so you have the idea i am getting at , i think there is a good thick layer of fiberglass and /or timber al the way thru my transon , im gonna call the guy who built the boat and find out

the pic is too far away to see it right.. nice craft ,none the less.. <br /><br />you can do what you want.. but still say it's grossly under powered.. an like i said,, 'you don't get somethin' for nothin'".. the fins will rob even more precious power..<br /><br />nice fish tho..!! REAL NICE FISH..!!<br /><br />let use know the outcome,, stop by anytime.. tell us about the fishin' over there..

Re: drilling into boyency tanks

those are sme REAL pike<br /><br />they fight like dogs ovr here<br /><br />the only thing is there becoming scarce becaus a lot of trout fishermen that catch pike accidently will kill them because the pike kill a lot of trout , stupid ****ers<br /><br />BTW , when u say its underpowered, most of the boats hwere have 9.9 and 15 hp on em anything more is far too much , im not sure what speed i get withmy 9.5 , its fast enough the only problem is the ass of the boat stays down in the water
