I saw a post for the ultiimate engine and thought I would ask.....my 330;s had 300+ hours on them when things started letting go. I know a guy with a 1989 Baja with a 454 mag with over 800 hrs on it!! and
he beats the crap out of it....nothing but oil changes.....

I've got 400 hours on carb MkIV 502 Mags. No issues. Compression within 8psi. Never been inside.

I bought a Baja Sport 280, twin 330`s, new in fall of 1990. We used it here at the lake for 12 seasons with very little trouble. I lost one motor at 666 hrs (yup as soon as the hour meter turned 666 it seized) I sold it Sept 2002 with 880 hrs and it is still running strong.

A buddy of mine has a '85 Formula 206 (260 Mercruiser )with over 1200 hrs. Never had the valve covers off.

There's a lot to be said for stock mild power!

I've got over 2200 hours on quad 440 Yanmars and Trimax surface drives.

I already had to change oil in those damn things

I believe that Devil Man (SCOPE member and founder?) had put more than 600 hours on his 1000hp Paul Pfaff motors. I can't recall what his OSO name is (and it might not be Devil Man), but I'm sure he'll chime in.

I say Too Old or Audio.

That would be the D-Man and the D stands for don't come to OSO anymore..

I have almost 500 hrs on my 454 Mag MPI. It seems to be running fine.
