97 Mariner 2.5 150 EFI Upgraded
126-132 compression between all cylinders. Heads cut by JSRE, ducas reeds, Bobs exhaust tuner, computer flashed to 175 promax spec, injectors flow tested and cleaned, oil injection deleted, new fuel regulator, and VST cleaned and inspected, new fuel lines, solid motor mounts. New OEM Lower Unit 1.87 ratio 1 year ago. Runs awesome, needed a little more motor for my heavy boat. Prop not included. Pushes my 19ft Procraft 67mph at 5900rpm. Everything is new 3 months ago.

Price? motor sounds like runs pretty good , never heard of 175 promax tho. Prob 150 promax tune which would support the mods done

No such thing as a 175pm but I would like to know a price, I'm looking for a 200 but might consider it.
