Re: need powerhead advise mercury 150 hp xri efi
Needs ta be looked at by someone that knows what ta look for. This is where tha experience part of a "rebuild" earns its dollars. A windowed (vented) block could take out tha crank plus do a lot more damage than just one hole. A good rebuild could get expensive really quick. Most of tha time a "core" won't fly with a hole in tha block and/or bad crank. Some will at least drastically reduce tha value of tha core. A "quality "rebuild" will have ALL straight, freshly honed clyinders, new rings, pistons, rod and wrist pin bearings (OEM OR LEAST NAME BRAND PARTS). Anything less is just a fix till next time (could be 10 minutes or 10 years) which I can understand when dollars are involved. DO YOUR HOMEWORK................There's lots a jerks out there.
Where are you located?
