Had the boat out for the first time this year! But, now that the lower-units been rebuilt, the engine is giving me $h!t.
1994 Merc 7.4l About 1,000 hours on it. Starts fine, but I need to give it some gas in neutral to get it going, which shouldn't be necessary if it's EFI, right?
More troublesome, it idles down low, at about 500-600RPM (I seem to recall it idling at 800 last year, and reading that 800 is where you want it to be). When I had it in forward idle up the river, it died on me twice. popped it in N and giving it a little gas, it started right back up. It sounds like its running roughly, but its hard to tell on a water-cooled engine that naturally has that rough "blub blub blub" sound anyway.
Additionally, the engine temps were reading almost null. I'm on Lake Michigan, and its freak'ing cold this weekend, but if the engines been running and up at 2500-3500 RPM for a half hour, the should the temps still be within normal operating temps? (wondering if the gauge / sensor is bad)
Any input would be helpful! Thanks!
