Sounds like a wise choice. If you shop around Im sure you can locate a couple F.L.s of the proper hp. Lots of them get swapped out for more modern, higher hp engines but on a trawler the more hp isn't going to make much difference but lots of people actually think you can get an old T.T up on a plane if you add enough horsepower. Sort of true but not realistic.

Like the old saying goes. "Speed costs money, how fast do you want to go?"

Dear Lehman friend.
Donate the existing Lehmans you have as anchors to a worthy boater and buy two rebuilt 120's. As you will recall as an attorney, the three words every attorney hates to read in a contract is..."Notwithstanding the foregoing".

I did speak with Mikeh and is a real nice guy. Still has the engines.

I'll start a new thread on the repower when we get to that point.

Cheers!

Does that mean keeping the 225 block so nothing downstream needs changing? I`ve a vague memory(perhaps generally but this one is specific)Comodave depowered his 225s, maybe deleting the aftercoolers. Might be worth a PM unless he comes and posts.

No I have not modified mine, they are still 225s. If the aftercooler goes bad they are not available. So if that happens then you can run a hose around it and then you get a 180 hp. I am concerned about mine because there is no record of the maintenance being done on the aftercooler so I don’t know the condition of mine, I can only hope they are ok, no signs of them having a problem.

As of the last check there were two F.L. 120's for sale on this forum. (Not me, not mine)

I'm going to replace the engines and transmissions. The after coolers on my 225s have been bypassed and rebuilding a 35 yo bit of a one-off engine and using 35 yr old gears does not make sense. I know I'm never getting my money back but trips up the inside passage without having to worry if I'm going to be stuck somewhere where I cannot find parts, priceless.

Mike has the FL120s for sale in the classifieds and we did speak, but the boat weighs 68,000 lbs (per the crane operator) and pushing that beast together with 24" x 24" props, might be asking too much for that engine.

Finally, this model is based (stolen?) on the Hatteras 48 CPMY and they power those with 425's DDs. Pretty difficult to tell the difference, huh?

A couple of 120s will push your boat ok but you may have to reprop. Lots of boats your size have 120s. It won’t be fast but it would work.
