If you were starting all over, would you buy a Hatt with DD engines again??

This 52 has Volvo's, but I cant get over the painted interior wood.

Interior is cheaper than repowers. I'd think it was worth considering if the cosmetics need to be done anyway.

Overheating them.

This is true of most marine engines, and for that matter most engines. It's murder!

Don't be afraid of 8-92's at 1500 hours. I have a pair, 2800 hours, pumped to 735 hp and they run flawlessly

Does your daily driver automobile have a carburetor? Do you use a rotary dial phone? Are you reading this message I wrote on a CRT tube monitor?

Detroits are old, they leak, they are loud, and they use more fuel. All that can be ignored. But also, they are getting more difficult to get decent parts for (and prices will continue to go up).

Some new engine designs are junk and break a lot. But a few models are super reliable (cummins m11, 8.3, 6.7...cat 3406, c18,c32). Some of the cummins can still be had 100% mechanical. The difference in performance, fuel efficiency, and lower cost is amazing. DD lovers also forget that most of these modern engines will easily do 5,000-10,000hours or more before rebuilds if used properly (and that is on plane, not hullspeed).

But when North Korea does the low altitude nuke detonation and fries all the computers with an EMP my Detroit’s will still run

Neither will you if you got your hearing aides in.

Sorry to disappoint but unless your DD's have a pull start rope as backup, you're not going very far. An EMP will fry the windings on your starter. Even if you over come that, you're only going as far as the on board fuel will take you.

The only way to win a nuke war is never to engage in one.

Got that covered. We just bump start ours. Just need to get it to the top of a hill.

Replace EMP with Lightning strike. Now imagine you get caught offshore in a bad thunderstorm when you get hit. Which engines do you want now?

I've had the 6.7 in a truck for years and I love the engine. Smoother, quieter and more efficient than the old 5.9 12 or 24 valve.

I had to go over the emission systems at 270k miles. I believe the po did clean the egr before I got her but overall a great running engine.

Its Interesting how it becomes less efficient when the pollution crap needs maintenance. It's also a drag on efficiency but I get about 23 mpg on the highway with 2x the power of the 5.9. Its certainly progress just not 100% since it would probably get 30 mpg without the tree hugger crap.

I'd be quick to embrace the newer technology over Detroit's in my boat. I'd love the smoother, quieter and more efficient engines. They have less exhaust smell too.

This is why people repower. I'd not throw out running detroits but I'd be happier with newer more modern engines.

Remember some of the higher hp engines do require significant maintenance. As do the cranked up Detroits.
