Starboard engine stalling when warm
Posted: Jul 27th, '21, 08:02
I thought I had this problem sorted out last summer but it has surfaced again. After running for about fifteen minutes at 2800 rpm my starboard engine cuts out and won’t run above idle speed. Give it more throttle and it stalls.
Here is what I have done so far:
Last summer:
- Replace the coil and ignition module: no charge
- Replace the fuel pump: engine would not start sometimes.
- Replaced the line from fuel tan to filter.
- Installed an anti siphon valve at the tank.
- Swapped port and starboard fuel lines.
- Mechanic at the marina took off the carburetor and cleaned it: stalling problem went away but it still had an intermittent non starting problem.
This summer:
-Different mechanic installed a rebuilt carburetor. He found a pinhole leak in the line from the filter to the pump. Engine starts consistently. I had put about six and a half hours on it, driven the boat about six times before the problem reappeared.
Any ideas?
