I bought a 30' superboat last year and it had Twin 2.5 Mercury racing engines on it.... engines have 110hrs; 160 compression all cylinders, both outdrives completely redone by George Fuller's in NJ. Considering going to more of a everyday engine as I do not race the boat. I heard these engines have value on the race circuit..... Does anyone know what the value would be? Model #'s are 2.5 LCLOS and 2.5 LLOS

I would say they are worth in the range of 10 to 12k a piece. I am assuming they have sportmaster lowers and yes there is an elite group of guys that are interested in them as they are the last of the 2.5 motors and are still used in stock class. I am assuming they are 2.5 280s but if you post pics we can give you a better idea.

Yes with sportmaster lowers and yes 280's.

Yes sportmaster lowers, 20", Yes- 280's counter rotating. Have pics/video running but not really sure how to post them on OSO

They are not as valuable on the race circuit as they were a couple years back, but they still have value.. The 2.5/280 with 15" Offshore mids and sportmasters demand the most money. I have seen clean sets sell between 18-24k.

2.5/280 with 20" offshore mids and sportys - 15-20k

2.5/280 with bass mid.. no idea.. lol

I actually want these motors, but don't want to be selfish

2.5's of all iterations need rings at 125 hours.

you stole that whole package for 20k that was my friends boat a little ruff around the edges but nice ,,i wanted it but lack of funds put too much into my new home ,,that would be nice with 300xs motors ,,,,,,

My recommendation would be the part them out. You will make more money doing that as 2.5 part are hard to come by these days. I sold a set similar to these last year and did much better parting them out than I would have selling complete.
