Mercury 1959 Mark 78A

Great parts look-up system. Too bad many of the parts for my Mark 78A are no longer available. Thanks for listing other dealers who may have what I need.

Their parts breakdowns are very good, but in my particular application, they were not all the correct part #s. Their pricing is very reasonable. Trying to get a real parts person to help you on the phone with the right part selections can take a while. All in all, I would definitely order from them again.

Problem fixed: complete tune up, oil change, impeller replacement, fuel system clean out, new belt, and other general maintenance items.

Work done at a service repair center.


Lots of hard to find parts in stock. Excellent customer service and fast shipping. Highly recommend!

Very prompt shipping with the items they have in stock. I've bought from them several times and will continue to in the future.

Problem fixed: Water leaking from spark plug hole.

I finally got the motor running after sitting for five years. I was going to let it run for a little bit since it hadn't been run in so long but when I walked around to the motor it had water trickling out of the top spark plug hole. I thought the engine might of had a crack somewhere but turns out it was just a gasket behind the water cover. Replaced it last night and finally got the motor to start again and no leaks so far.
