Help with Mercury Outboards
 

I have a 1985 175 Black Max (oil Injected) 2.4L Outboard that has a bad piston. I was told these motors have sleves that can be replace with a new piston, but I don't know it that is the best thing to do. I also don't want to drop 3 grand + for a whole new powerhead. What is the most cost effective and reliable method to take??

Nothing at all wrong with sleeving a cylinder. Its done routinely in both factory and high performance motors alike. From a reliability standpoint, a sleeved cylinder is typically the least of worries.

what are some other concerns I should know about?? Will the motor still have the same horse power after it has been re-sleeved, and the piston replaced??

Assuming it is rebuilt to factory specs, there should be no other issues. Horsepower may increase slightly depending on how worn the rings were originally.

They will simply remove the original cylinder wall material, and install the replacement sleeve. This sleeve is often thicker than the factory cylinder walls, and depending on the material used, can be even more abrasion resistant than the factory cylinder wall or sleeve.

thanks for the info, I'll start getting prices today.
