    help with running surge brake lines

    Instruction say to have 2 T unions but it adds a lot of annoyance to the routing of the cable. Is it ok to not use that first T union with the plug from the actuator (the X in the photo) and go straight into the union that connects to the brake (the arrow)? Wouldn't it be one less point of failure?

    It's been a year since I needed to use my 2002 15hp 4 stroke. I had an idling issue with the motor recently where it won't stay on. I took the carb apart and cleaned everything out and it fixed the problem. At the same time I installed new plugs. Going to do an oil change tomorrow. I hardly...

    Does upgrading from points to electronic distributor help?

    When I said does it help, I'm not even sure what. I just read that it's better but for those that did the upgrade, did you see a difference? My boat runs fine now, I threw out the ford 302 and got a chevy 350 motor in there so power isn't an issue. But if it runs quieter and smoother and...

    Merc. 888 and 302 grinding sound

    I have a friend that has a 1974 boat that has a Ford 302 and a Merc. 888. Funny is I noticed that when the engine is idling (not in gear) I can hear small grinding/banging sound on the rear side of the engine by the outdrive. The engine appears to be smooth though. When in gear the grinding...

    What's a good material for DIY boat windshields/windows

    It's time for me to replace my drop curtains on my boat that has a hard top. I'm thinking about making them out of hard permanent materials like the windshield and make it more like an alaskan package. Before I start with planning it out I'd like to start with the type of materials.

    I have a 21ft Striper with a Cobra SX 1:66 Ratio, I just repowered the old 5.0l to a 5.7l.

With the 5.7l i have now, i believe WOT...

    I just spent some pretty penny rebuilding my bennett hydraulic trim tabs and replacing the old rotary switch to a toggle style switch. After getting everything installed (was in a hurry) I realized the hydraulic pump and the switch cost me almost as much as the Lenco electric trim tabs. I'm kind...

    Any decent aftermarket FWC kits that doesn't cost a right arm?
