I have a 88hp V-4 SPL when I have it at full throttle for about 5-10 minutes the motor bogs and sometimes stalls, however I can get it to recover by pushing in the choke or I start it back up and it takes off. Could this be electrical or fuel, if electrical what component should I suspect. The motor runs great when it is running, compression is 127 psi all cylinders. |

Recovery with choke proves the problem to be fuel related. Try cleaning the 4 high speed jets. If they are slightly fouled, that would cause a slight lean condition.
Thousands of parts in my remaining stock. Not able to list them all. Let me know what you need and I'll look it up for you. Visit my eBay store at:

i run a 1994 88....you can clean those jets in 30 minutes max using a jet clean out tool that welders use..they come in all sizes in a little thing that looks like a feeler gauge set but have little wires instead of gauges..you could also have a airleak or a partially stopped up tank vent..choking the motor is just overcoming a feed problem..could be anywhere in fuel lines or system..i would also add a mix of seafoam to gas.. |

If yo have a ball on your fuel line check and see if it collapses when running. You may have water and crude in your tank that is blocking the pick-up inside the tank. |
