Looks real good I love the bilge. One thing to think about , If you get an oil leak those black engines wont be easy to see. i painted my Scorpion chevy orange and the Formula engines are gonna be the Merc blue. nice score on the carbs. My new 454 arrived yesterday looks awesome.

sounds like a nice solid engine.
not much duration or overlap on the cam from the sound of it.
Whats the LSA and centerline?
Duration/ lift?

i am thinking about making a run stand for the new mills is there anything to take into consideration? should i put a guard where the flywheel spins to keep it safe? what gauges did you use?

We went with a High Energy/Marine™, 260H: Cam & Lifter kit from Comp. Duration 260/260, Lift .440/.440. Im pretty happy with the way it idle. Im not sure what horse but im hoping its close to 300.

Toasty,

The stand was pretty easy to build. I basically just made a copy of the stringers in the boat and used all the mounting brackets that the boat uses. A guard probaby wouldnt be a bad idea. since i have the tranny bolted up to it i wasnt worried about it. The gagues i used were some cheap mechanical gagues from summit. oil pressure water temp and voltage. picked them up for $20. a good tool to have for the first startup.

can beat a run stand for break in especially on boat engines. It sucks to get it in and then find aleak or another problem.

Thats part of the reason I like the OB's so much they are easily accesible where I/O's make you a contortionist.LOL

There are many beneifts to I/O too though. Like the ease of finding parts for them.


I am assuming that 260 is advertised not at .50?

Here are some before pics of the starboard motor.









Got most of the motor disassembled last night. The internals look pretty good but the crank will probably have to be sent out to be ground.
