We did not want to scratch them! Those will go on when they are headed for the bilge!

good call

What efi system did you use?

Re: New Tmp Motors!
 

Thanks John and everyone. We've been working on the development of these engines for over a year. This engine package is dialed in, and ready for the Poker runs.
They are 598's, Hydraulic Roller, pump gas 91 octane, ( but could run on 87 in a pinch). The computers are Mercruiser with a custom designed program, wiring harness, injector system and fuel system.( This allows them to be serviced by any Mercruiser dealer) Tests have yielded only oil changes and transmission service over 100 hr intervals. We are currently building another set for our shop boat that we will stretch to 150+ Hrs. before rebuilds.
We will also hopefully be debuting a new 1600HP engine at the Miami Boat Show.

Which Mercruiser system?

Re: New Tmp Motors!
 

Considering they are a hydraulic roller set up, what hp are you developing at 5200-5300 as that is probably the max extended operating rpm?

Re: New Tmp Motors!
 

I'm green with envy! Very Nice.

Re: New Tmp Motors!
 

Newer hyd rollers are good to 5700 sustained (per Isky).

Hey,TMP, PM me a ballpark price on a pair of these. Dynoe'd and shipped on a pallet ready for installation. Complete bobtail with flywheel, alternator, raw pump, etc.

Re: New Tmp Motors!
 

The engines made over 1000HP from 4600 to wide open. At 5300, they made over 1100HP. The lifters we use are good for 6300 RPM's. We've tested them in engines for over 100 hrs w/ no problems at all. They are custom built for us.

We use both the MEFI3 and 4 depending on the application.
