The engine bay on the boat is huge, so installing wasn't a problem. BTW Original 454 had spun bearings, block was to far out to line bore. Machine said it could technically be done(think he said "shimmed or welded"), but not good idea for boat.

I did have several other options form the dealer. He had two more 454's that were stock. The purchased engine was the cheapest. The stock motors had lower hours and well are probably in higher demand. Also it's likely the previous owner beat the engine. Especially if he wanted more.

The motor was fresh out of the other boat. It was shrink wrapped on a skid. It was basically ready, just needed carb, dist. and installed. I did replace water pump.

I did also run the cranking vacuum test the other day. I forgot to mention it. It not something I've ever had to do before, but seemed simple. Unplug dist. make sure throttle plate closed. "T" into base of carb. I got nothing on the test.

Also I did use starting fluid. But with the ventilation problems in boat I decided not to use again(the smell lingered for quite some time, even with the blower on). I don't recall the boat starting with it.

I'm hoping it is cam/crank out of time. I really need to test the rest of the cylinders. I did 2-4-6 and when I seen 8's numbers. I called it quits for the day. It was a rough, long day and I was fed up.

Again, once started and major advance added. Motor did well. Response was good revved nice, sounded good. I didnt rev high, maybe 2500. Timing didnt advance much either at that RPM.

The oil is likely got some fuel in it. When I did the compression test two of the four new plugs had fuel on em. Oddly other two didnt. My only guess was the Weiland high rise wasnt spreading fuel evenly. Maybe someone else has another reason, I'm not aware of.

Water fuel separator is new. Guess I probably need to get check valve.
Outdrive is Volvo duo prop.

I had no warranty. The price range I was in, really isnt one where you can get warranty's. It was this dealer or take a crack at one on Craigslist. Figured my odds where better with this dealer. Maybe I should have just held off, saved and had one built. Hindsight is always 20/20.
well i do not know that you paid . i do not want to know.... But there long blocks on E bay . that are not bad on price . for what it.s worth i have a 330 hp 454 mark 6 long block fresh and a 496 mark 6 454 roller enigne both marine engine. i will stand behind them for work and parts.i build and machined engines every day
