A friend runs one in his 29 Scarab, no probs but He really babyed it . He's got around 300 hrs on it, Only issue was with the blower, oil was spilling in the bilge area. Eared they generally need a rebuilt(Blower) around 250-300 hrs, other than that, looks like a really strong engine.

Great engines,turn key. Like JS232 said, blower rebuild around 300hrs otherwise bullet proof. My blowers leeked a little oil from the fill screws. I was told by B&M,now Holley,to replace original screws that have pin hole with one that doesn't have hole.

I am right at 90mph now. I am running 34 bravos with 1.65 gears. I am still up on the rev limiters. In the process of changing gears to 1.50 and adding nose cones. Hopefully will be able to run same prop when labbed.

Interesting numbers!

Your boat seemed to handle the big stuff pretty well on the last milk run...

Not well enough! I thought my windshield was going to break a few times. The last leg we couldn't keep the props in the water. We put the Bravo's to the test that day. Bigger tabs may be my next purchase.

Do a search for 525SC. Lots of info has been discussed about them.

Its been a great engine for me. Very reliable and turn key.
