Hey guys.
You fellers are that good that I decided to hit you up for advice again. I got a 40 hp mariner (40 E 6E9 s 104752), 1985 2 cylinder outboard. Basically a copy of those old Yamaha fm series.
I recently posted how my motor was overheating, and I found 2 broken veins on the impeller. I'm after flushing the water tube out with the thermostat and bypass valve out with thermostat cover off, inspecting everything except for the exhaust are (i.e. were the spit hole tube is originally coming from).
Will I do any harm taking off the exhaust cover without having to buy new gaskets? I there anything I should watch out for?
What torque do I tighten the thermostat housing bolts when I put them back in?
What torque do I tighten the exhaust cover when I put it back on?
I appreciate any help.
All the best.
Robby
