Just started using my "new" boat with this motor in it. Runs great, has 350hrs on it and it purrs like a kitten and has lots of power. (47mph in a 18ft fglass deep V). Temperature gauge doesn't get much over 150F once warmed up. <br />Anyways, the only thing is, it seems to smell a little like antifreeze/coolant when it's running and when I look at the motor it is green where the exhaust reservoir tank bolts down to the exhaust manifold like the gasket is leaking a bit and dripping and getting hot and making the smell. I ran a tank of gas through it (say 40-50 miles of use)and when I checked the antifreeze/coolant level there is none in the reserve/plastic bottle but when I pop off the "rad cap" off the exhaust reservoir tank its full, so maybe I lost a pint or less in a day. The plastic bottle was to the full cold line when I checked it before I used it. There is no antifreeze/coolant in the oil or anything like that so it's not a head gasket issue. I was wondering if I just need to tighten the exhaust reservoir down (4 bolts) to seal it up where the gaskets meet or if this is a common repair (replace gasket). Also the reserve tank is tucked up under the engine compartment and I don't know how the heck you would ever fill it. Do you just add it at the engine and the plastic tank fills up when the antifreeze/coolant heats up or what?<br />Lastly, I know I have great oil pressure when I start the boat and it also is well over 60lbs at WOT once it gets warm, but when I drop it to idle after it warms up it drops down about 10-15lbs. Seems a little low but it could be a gauge inaccuracy thing or is it normal for them to have low oil pressure at idle? <br />I have a manual but it really lacks some detail and was hoping someone with experience could offer comment.
