Re: 220 Overheating - I'm about to give up.

I'm sure youve gone through all this stuff ...

hey pc, thanks for the piston info, do you have any sugestions for cost and good places to buy?

Re: generation 3 electronic ignition module

hey Bob. keep in mind that the brake is just a plate that drops at the back of the boat, the more down pressure you apply the better it works. It will help you track and can get the boat back in line if it gets away from you. The best i can describe it would be to pretend you had an anchor tied to t...

propeller performance

i understand that a stick prop is more for high end and a paddle prop is more for bottom end but don't understand where these 3 and more blade props come into the equation. I run a paddle prop that has more bottom end push than i need and would like more top end. At the same time i don't want to giv...

Re: generation 3 electronic ignition module

Bob, do I know what you’re talking about! we mostly run on the lake but have a few land portages that can get downright scary depending on the conditions. that is exactly where the brake really shines. keeping in mind there is still a lot of slip you get enough brake to keep the nose going where you...

Re: generation 3 electronic ignition module

Sorry Wild Bill, i missed your location on the post. Firstly, i don't want to take any credit for the design because a guy named Lenard Roi came up with the brake and boat design years ago with a full history that I wont go into. The brake works well but it's kind of like reverse on a boat, you know...

Re: generation 3 electronic ignition module

thanks for the comment. My mags have never failed but I like the idea of electronic ignition for stronger spark, smoother running and easier starting. Is there any system out there that works on a 470 that you may like? the plate on the back of the boat is a brake and a trim tab working of a cable r...

Re: building old 470-13 for power??
