....test run of a used OMC (G.M.) 5.7l v-8 I bought last year for $150 (USD). Kicking the moth-balls out of it and prepping for sale.

 

So what heli are you going to put this beasty in? Man thats a good pickup for 150usd..

 

By the look of it it goes into an RC boat....water cooling and all..

It's going in a boat that originally has a 5.0l in it. I'll make $500 on the engine block alone. Will part out the rest.

 

nice, a bit of wake boars action

 

Right, those kind of boats typically good for around 80kph or so.

 

Meanwhile, on the opposite side of the planet..... this is what I'll be doing while the Fun Fly is going on. Enjoy.

 

Nope. Gig cancelled. We have freezing rain... ice on everything, it's nasty out there. So I'm limited to flying the Nano indoors, bumbling around in the garage.

 

Finished conversion of OMC Cobra block to Mercury Marine.

 

Is the cobra block a 4.3 liter? How many ponies does this thing create? Nice skills by the way...

 

In both cases, same GM Marine/Industrial grade 4.3 v6 rated 175 to 205HP depending on what carburetor and intake manifold is used. The change-over is simply a matter of removing both engines and transplanting all the external Mercury accessories to the OMC block..... then installing entire engine assembly into the boat. Then there is only test running and setting timing and idle settings, and its done.
This particular job was installing a good engine from a boat with rotten wood supports to a newer boat with a freeze-cracked block due to improper winterization. (someone didn't drain the water out and it froze and cracked the block beyond repair)

 

How long did it take? You sure know your way around a motor...

 

Hey pretty cool @Beaver. You can really smash out the drums! Rock On!!! Lyrics is good to! You need to get your buddies into helis!!!

 

Actually, my guitarist got me started with a micro-chinook he had, but he didn't take to helis like I did. He's more of a gamer.

 

All said and done, pulling two engines, change-over, and putting one back, about 10 hours....
It's just what I do for my day-job.

 

I'snt that what welshplugs are for?

 

I think they are for over pressurizing due to heat, not freezing
Simon

 

On a

The plugs are to relieve pressure in both cases, but an engine block full of straight water will push out the plugs and still crack the block if frozen hard enough.

 

You must be an expert at loosening tight bolts or stripped threads? Broken or siezed bolts? Thats a fast turn around for a motor changeover. Impressive @Beaver.
