Not to sure what is going on, but was told to look at the electrical. So some basic information to start off with;

1985 Evenrude 90hp V4 VRO (VRO removed and use premix gas (50:1))

This winter I rebuilt both carburetors, new fuel filter, new gas line, new started gear, and replaced all the spark plugs. I was having this problem last year. The motor is cold hearted but will start up fine. This weekend I was out running at WOT for a while and the motor just stopped. It would not start right back up. But after 45 min or so I tried it again and it fired right up and ran like normal. I moved to another fishing spot and tried to for 15 min and thought I would try some where else. Again it would not start. So I fished the hole a little longer and tried the motor again. It started right up?!? It seems like I almost need to wait 45 min after each time I run the motor to get it going again or it won?t want to run.

What could this be :confused: Thank you for your time and help.

sure sounds like something is heating up and failing. do it again, and check spark right there in the water, when it fails. you have 2 power packs, one for each side of the motor. if one side does not have spark, look at that power pack.

I have a power pack for a 140 hp Johnson v4, would that work on my 90?
