Well, everything checked out great with the 19 foot polar. Left it with a mechanic at lake hapatcong. He did a compression test, all 3 cylinders were at 100, which he said is good. changed the lower unit oil and did a pressure test, all checked out. impeller in good shape. Then he told me he "lake tested" it. ran well. All switches for bilge pumps and live wells worked. The only thing on the boat that did not check out was the tach. I feel that should be working so I don't over rev the engine, he is fixing it.

Now for more advice..........

what kind of oil should I use in the injector (90 HP saltwater merc)?

should I use stabil every time I put gas in?

what is the best way to flush the motor after using it in saltwater? When I put the muffs on there was not enough water circulating thru the motor to come out the coolant output port (or whatever you call it). Am I going to have to start the motor at home in a barrel?

Thanks for the help. I am as green as they come as far as boat maintenance
