Hey all, I have a 2001 Evinrude 15HP four stroke E15RVL4SIC (BRP not a Suzuki) that I use as a kicker for trolling on my 22.5' walkaround..* It is tied into my main tank via a 3 way ball valve ahead of the main fuel filter but with its own inline filter to seperate it from the big motor.* The motor will run and troll perfectly first thing in the morning up until high noon or a little after..* Once the ambient temperature outside starts to get hot 70-75+ the motor will start to sputter and (wet) fowl plugs..* If I take the hood/cowl off the motor it will clean itself out and start to run normally again..* Put the hood/cowl back on and it will sputter and foul again..* Once the ambient temperature climbs above 80 degrees taking the hood off no longer solves the problem..* The only way I can then solve to problem is to use the cover for my Humminbird 1158 as a fan and fan air across the motor..* That will stop the sputtering/fouling until I stop fanning air and then it will start sputtering again..* Sometimes, even all it takes is a little breeze to blow up with the hood off and the sputtering quits
Parts I have changed to try and resolve the issue to no avail include:
Waterpump impeller and all associated parts
Thermostat and housing seals
1 heat range hotter plugs
Thanks
Adam
