Boat wont start after running.

[Zachwest34]

I have a 1999 evinrude 70hp fuel injected. If I drive the boat until it's fully warm. It will not start again for approximately 10 minutes or so. This started out of no where. But since this issue started I've replaced all fuel filters and fuel hoses aswell as ball pump. Still have the issue. Sometimes after 10 minutes if someone pumps the ball it helps somewhat but not always. I've suspected the fuel pump but not too fluent in outboards. Any suggestions? Thank you

Had a similar issue . The cause (for mine) was lack of crankcase pressure. Hard to diagnose. Tightening a few bolts solved it (for me at least). Good luck

You know which bolts? I've been dealing with this for like 2 years now.

That 1999 70 HP is a fuel injected 4 stroke ( Suzuki ) and crankcase pressure is not an issue I think.

What is the temp when it is acting up? (top of the heads)

I have not checked. But I can use my infrared thermometer to check. Do you know what it should be at?

130-140F or less when warmed up. 160F is overheating.

Maybe overheated. Try new thermostat and impeller.
