Got a couple Detroit buddies that said to run away quickly! The engines in this boat are tickin time bombs cuz the horsepower is turned way up.
What do you guys think? And does anybody know this boat?

Thanks!

A customer in Daytona had 3500 plus hours on a pair before he rebuilt them. They were starting to lose a hundred rpms at wot and a bit of extra smoke.

Some of my friends back in Baltimore had these TIBs on larger boats which probably meant they worked harder. Their view was expect 2000 hours on them. My son had them in a 46 Silverton and they were tight, no smoke. I'm not sure of the hours, but could find out if you want.

A dockmate had a pair in an Ocean 45. Seemed to run fine, but very sensitive to HX fouling/overheating. My friend was constantly cleaning them.

At least they aren't 53s. Our old 871 TA's only made 485 per side. Those are definitely tuned! I'd check the coolant and see how much they smoke if your seriously looking at the boat.

BTW, All Detroits are ticking time bombs IMHO. Haven't been made in many years. Hard to find service shops. They all smoke. Uggh!

That makes sense. HX probably was designed for +-300HP and now its 170% of capacity.

The only Detroits that are "ticking time bombs" are the ones that have not been taken care of with regular and proper maintenance. If you see nasty oily engine spaces full of nasty oily rusted engines, the owner is not taking care of the machinery no matter who manufactured them. Those are the "ticking time bombs" you want to stay away from.

The 485 TIBS are at the edge. I would have to know the detailed maintenance history and, just as important, how much fuel has been run through them before I would commit to a set.

Just my opinion. YMMV

Jimmy lovers!

I have just been getting spoiled by new Volvo IPS and MTU powered boats lately so It's hard for me to want to crawl back into our 37 year old engine room!

One should be able to walk around, crawl around and lean over the machinery and not get dirty. The age of said spaces and machinery should not make much difference.

Those 2000 and 4000 series MTUs are spectacular engines. Volvos not so much due to a bad experience with them a number of years ago.

I second that.
