Rebuild/Repower 32' Topaz

Greg S · 11-06-2009, 01:21 PM

We are rebuilding a 2006 32' Topaz that sank off of N.Y. The boat is being repowered with a pair of Cat C-13's rated @ 900 Hp. each. Our goal is a 40 kt. cruise with reserve. We thought we would share pictures with you, Thanks Greg

My initial thought is.....

Way too much power.

have been following this build on another site.

TA (Turbo aftercooled) versions of C 9's are rated at approx 1 hp per cu in. Your modification is generating almost twice that.

I dont think you can put those demands on that size block and expect any longevity or reliability.

I do wish you guys luck.

PS That Topaz hull will beat you to death in 3 footers. Had a 38, pounded pretty bad in a big chop.

You're a brave man. And an optimistic one too,

but I'm really intrigued by what you're doing here, so please keep the pics and narrative coming.

1800 hp in a 32 footer??? Good luck on the project. Frank

yes,fully agree-that sounds like excessive power.I think that it is ideal in a vessel that is 17-20 tons or so!! just a guess!!

lsp · 11-06-2009, 11:11 PM

Original power?

More pics. I love it, and you can never have to much power. You can have to much weight, but never to much power!

We bought the boat in N.Y. and shipped to Ga. Then spent 3 weeks pulling everything out of it. Everything going back in is new or rebuilt, So far the genset is the only rebuilt from the orignal Topaz, evrything else is new...I have work with Cat, ZF, Acme & Veem props to get the drive line size correctly here are some pictures
