    Exhaust in engine compartment

    I have a 1990 90HP Force outboard on which I just changed out a couple of pistons based on Frank's great instructions. It runs great at full throttle, but I am having some trouble getting the idle set so that it does not stall when going into gear. As I was trying to adjust the idle speed on...

    90HP correct battery capacity?

    I need to get a battery for a 1990 90HP Force and have no idea what would be the correct capacity. I see that they can range a fair bit in price from some of the smaller CCA models up to the larger ones. Any guidelines on what to get that would be enough to crank this engine over? Thanks

    Should fuel filter be full?

    I recently replaced a couple of pistons in my 1990 Force 90hp through the reed ports by following Frank's excellent instructions.

    Anti-seize or gasket sealent for bolts?

    1990 Force 90hp Impeller Replace Tips

    I am about to attempt an impeller replacement on my Force 90hp. I have the Seloc Repair Manual, but since it covers such a wide range of Force outboards I'm not sure which procedure I need to follow. There are 5 different sets of instructions for water pump servicing over 15hp motors: 1) with...

    Owners Manual required reading?

    I just purchased my first boat, a used 1990 Bayliner Capri 1800 with a Force 90HP outboard. The previous owner did not have the owners manuals for either the boat or the outboard, however he did give me a Seloc manual for the outboard. I was wondering if there is any really useful information...
