I drove 20 miles to the Mercury dealer to buy quicklean to use in my 2000 Optimax 150. The dealer said Mercury does not recommend using quickclean in the Optimax, in fact he said you should never use quickclean in an Optimax because it raises the octane which is not good for an Optimax.WTF! Any...

Replacing oil pump on my 2000 Optimax 150 due to leaky pump. Now I see a few of the lines coming out of the pump are leaking as well, 2 at the pump end connection and one at the engine connection. I have removed the lines, trimmed the ends a hair and reattached with new ties, but they still...
Guess I need to replace the oil pump in my 2000 Mercury Optimax 150 due to small leak around electrical connection. In priming the pump do I move the throttle handle 3 times forward with it in gear or should it be in neutral?

year 2000 Optimax 150. Been getting intermitten over heat buzzer but telltale and pump seem to be working fine. I will be checking and replacing impeller this week and want to make sure any debris in the lines is cleared out as well. What is the best way to do that? Blowing air? If so through where?
Year 2000 Optimax 150. The Outboard was all the way in the down position already when the tilt motor turned on to the down position, thank goodness. I cut the outboard but the tilt motor kept running. I first thought it was the bilge pump as the sound seemed to be coming from the bilge. The...
Gearing up for Salmon fishing, I recently installed a 4 cycle 9.9 hp kicker motor. To hook up the fuel line I was planning on installing a fuel/water separator directly in from the boat fuel tank and both lines out, one to my 150 Mercury Optimax and the other to the kicker. The Optimax 150...
I just replaced my old disc brakes with new Tiedown G5 disc brakes with new rotor/hubs and adapter plate. Problem is when I put the wheel back on the caliper rubs the wheel. I guess as fix would be to try different wheel design or maybe adaptors to put the wheel out a bit. But wondering if this...
