mercury 1972 blueband 80 hp has hole in metal between exhaust outlets in cylinder mating surface and extention plate, ive had the plate rebuilt but not sure how to go on with the cylinder block, would it be alright to weld with powerhead still complete
<br /><br />Your engine is an outboard, not an I/O or inboard.<br /><br />I will move this to Mercury/Mariner Troubles.<br /><br />Good luck.
