Well, the cracked block/ JB Weld repair is holding great.... the new impeller is pumping water great... Two new things... Checked outdrive fluid level and it was off the dipstick!... Added 9 oz.. but no visible water in the remaining fluid.. Found fill screw loose!... Tightened the heck out of it and then put silicone over the screw just as added security... The boat sat for a week since last used and I saw a brown spot under the bullet and (hopefully) most of that 9oz. leaked out drop by drop over the last week and not the last time we had it out... Anyways it purred today and no abnormal noises or sounds... I think I got REAL lucky.. However, that being said, when I was watching the engine to see if my JBWElD repair was holding (wife driving boat, 3000 rpm, 3.0 liter OMC)I saw occassional "Misting" from the flame arrestor... It was a very humid morning with the temp and dewpoint being the same.. Hoping this was just water vapor?... put my hand around the arrestor and after it misted a few times I smelled and did NOT smell fuel... Engine oil is honey brown and so is outdrive fluid... thoughts?
