I've got a pair of 1990 Crusaders (electronic ignition). I splashed the boat earlier this month.
The port engine runs fine at low rpm. When I push it up to cruising speed (3100 rpm) it runs ok for a while but then starts to run rough and lose rpms. When I throttle down, it smooths out again.
I thought it might be bad gas, so I changed the filters, put in "dry gas" (not the alcohol kind), and switched from front to rear tanks. Still doesn't run properly.
Any ideas?
