Doel Fins

[digimortal777]

I have em on my 15hp johnson on my 17' round bottomed row boat<br /><br />when runnin today the boat seemed to want to rol a lot if i tured the engine , if i trim it out 1 or 2 holes will that stop her rollin , it never happened when i had my 9.5 on it with the fins on

Re: Doel Fins

Now you have more power, and with a row boat with no keel.......she is going to roll. You are probably going to have to live with it until you run across another hull.

Re: Doel Fins

forgot to say , it does have a keel , about 2 inches of one , its a good handling boat , these are the only types of boat people on this side of the atlantic use<br />also if i take off the fins will i need to fill in the holes, i have an anode that i took off the engine to put the fins on

Re: Doel Fins

digi, How wide is your boat?A narrow round bottom can be really sensitive to prop torque.<br />I would try trimming out but I dont think it will help.Try it without the fin, also you could check to see if you can raise it virticaly If the fin is too deep it might cause problems.<br /> A round bottom boat will roll a lot when turned<br /> As a crazy kid in 56 I could roll my 14 ft Crestliner 10 hp.(with 3 keels) till water trickled over the side.A friend could do the same<br />with his big 17 Crestliner with a 35. Crazy and stupid but it was easy with those rounded hulls.<br /> These were actually only semi rounded bottoms.

Re: Doel Fins

i cant raise the motor vertically<br /><br />ita about 5 foot wide<br />im thinkin the fins are the problem i might end up puttin home made tabs on the stern to lift the back up

...and no, the holes don't need to be filled.<br /><br />c/6<br /><br />Hooty
