Boat idles fine and those rpms were engaged with throttle engaged in forward gear. Still though, why blow that fuse 5 times in a row on the lake but not in the driveway? And why no energy fluctuations as rpms increased? You would think that if that fuse blows repeatedly on the water, then...
About 4000 rpm. Kept it there for about 20-30 seconds at a time but wasnt sure that the muffs supply enough water to allow that without burning something up after a prologued duration. With throttle fully applied there must be some kind of limit or governor because it waffles between 3900 and...
So here are some electrical readings I took. May not be helpful at all but i figured I would post them. The voltage over the alternator posts is a consistent 14.4v when running even with increased rpms. I measured amps over the 15 amp fuse and it went from around 4 to a little over 6 as we went...
But one other thought on the TKS that was brought up before.... this boat would “diesel” after you turn the key off most of last year. We would have to wait 20 sec or so before the kids could jump in the water for fear the motor wasn’t completely off. I wonder if the TKS diode is going bad as...
Going to borrow a set of muffs and test alternator on the trailer sometime in next couple days. My mechanic thinks that is what to test next as well. The reason I will do it first in the driveway is that our house is both 15 miles from our mechanic and the lake!
Here is the fuse and the serial number. The harness was purchased from a dealer who matched it to the engine serial number. My mechanic is very well respected and I believe will figure it out but its one of those frustrating trial and error issues. He thinks the alternator may be overcharging...
Its not the main 50a breaker. Its one of those watertight fuse holders in line. The harness is oem from Mercury as was the starter we replaced. From the factory it contains a 15a fuse. On the old wiring harness, which someone obviously messed with to deal with this gremiln, they patched in a...
My 2007 Tahoe boat has a 4.3 Mercruiser carbureted engine. The engine is newer, maybe 6-7 years old and the harness is brand new. The old harness had a breaker wired in where this one has a fuse. The fuse is a 15a and is on the red wire with purple stripe on the top of the engine. Is this the...
