Thread: Boat motor problems!

Grate advice everyone going to clean the filter empty the tank put fresh gas in & new hose from tank & clean the carb.

I use a filter on all my outboards. You ever look at all the crap in the bottom of a gas tank!! Doesn't take much to clog up the jets.

I'm a huge believer in Sea Foam. I put it in every can of gas I buy, every time. I keep a can of it in my boat at all time and put some in every time I fill my tanks. It acts like a fuel stabilizer. I started and drove my son's old pickup truck that's been setting for almost 2 years with the same gasoline in it. But when we knew we were going to set it up for a while we put Sea Foam in the tank and ran it for a while to get to the injectors and else where and 2 years later it started right up. It's good stuff.

Thanks again for the help everybody! I'll get it out this weekend and see what happens.

Hey fosh just an idea. Trimmed all the way down? Had my 25 horse at about half trim and tried to take off this year. Did exactly like ur sayin. Thot my motor was screwed up. Rev rev rev sounded like it wasnt gettin power and wouldnt plane. Dropped tilt all the way down and ran like a scalded dog. Sometimes its the simple things...

I've read all the post so far, I have a 130 Yamaha this year that was hard to start, and finely get started it did not want to get boat up on plane, but once started the first time it would start good the rest of the day, but still did not want to get boat up on plane, The pump cant supply enough fuel for the demand. My problem was fuel starvation. A fuel pump has a diaphragm that loses its shape, and loses it's ability to pump fuel pressure adequate. You would think pumping the line bulb up good and tight that would be good enough but it's not. A fuel pump is a ware item, and a u do it yourselfer easy fix. and not that expensive. I am like buckrub it's in the fuel.

try these easy fixes if they don't work I'll check the fuel pump thanks.

Do you have the vent open on the gas tank? Also, check for tight
fitting clamps on all fuel lines. If any are loose, it could be sucking air under load and not leaking gas when idleing. I had that happening on a 115 Evinrude and I like to have never found the problem. All it took was two turns of the screwdriver on one clamp and problem was solved !!!
