" I put the boat in the water
" I put the boat in the water this weekend, but it would not stay running. When first starting it would idle fine for adout 30 sec and begin to decrease RPM and then spit sneeze once and cut off. Once up and going it ran fine at mid to full RPM but would not idle long and died out on acceleration from idle.
The compression is 112-120 psi on all cylinders new omc fuel bulb with straight through fitting (no anti-siphon valve). The VRO and pulse limiter are new and I think the carbs are clean.
I took the boat to the shop and they told me if there were no fuel problems it could be the Labyrinth seals or sometimes called seal rings letting fuel get from one cylinder to the back of the piston on another cylinder, causing it to sneeze and cut-off. The shop said, "if it was the seals I would need a new motor $8,000.00. Yikes!
Does anyone know what these seals are and if this is likely to be the problem ? What if any alternatives do I have to get fishing again?
Thanks in advance for the help,
