Little more info for you all.
The injector
pump is brand new.
The transmission is brand new.
All filters are new oil and both
fuel.
Bottom was clean at last haul out month and half ago and 1000 miles of offshore sailing.
No noticable smoke. (some soot on transom after ten days at sea running engine for about fifty hours charging batteries and propulsion etc)
Replaced oil cooler heat exchanger upon return had one tube leak oil into raw water
exhaust discharge.
All temps & pressures nominal.
Max revs in neutral 3800rpm, max revs under load 3600rpm would suggest the prop is of correct size or close, recomended
delta is 200 to 250rpm.
Just as a foot note, if you own a W40 and you have an oil cooler heat exchanger normally mounted on the stbd side of the engine check it for zinc there is a small plug at the bottom my old cooler did not have a zinc (I assume it corroded away) but the new unit did have a zinc. see attachments
