1998 Yamaha 130 alarm sounded and motor died. I cant read my gauges but I believe it was the overheat alarm. Pulled the cover and heads were hot. Got towed in but motor started back up after cooling down so I could dock it in my slip with no alarm.
New water pump just installed, de-carb, new plugs, and cleaned the carbs. I just bought this boat and it had 25 gallons of gas from last year mixed with 30 new this week non-E gas. New water separator.
I cleaned the carbs myself and set the idle screws 1.25 turns out. That’s where they were set before. Sounded good.
So thermostats, or blockage in the head, or could I be running lean?
the 2 stroke 115-130 do have some issues with a gel building up inside the water jackets, blocking water flow, and flushing wont help, you have to pull the heads and clean it all.
Chris, that is what I thought by doing some web surfing. What is your price to do so and is there anything you would recommend replacing while inside? How easy is this to do if I tried it myself? The part I’m nervous about is striping a bolt.
Many people post there problem and ask for advice and once solved they never post what the problem was. Here’s what I found:
Pulled the t-stats and one was stuck closed and the other stuck half open. No build up on the inside so hopefully the heads don’t have to come off. I believe the original owner never changed them. Going to run the boat to see if that solved the problem.
