rebuild vs New motor

[macojoe]

I bought a 4 stroke last year and it was way to heavy for myboat!! Scuppers under water all the time leaving water in back! I just traded it with a buddy for cash and a HDPI 2 stroke, IMO $ strokes on older boats are a no go cause of the weight!

My boat is not a V20 any more its a 23 Sea Ox 225 was 4 stroke at over 600 pounds!! now a 200 HDPI

Rebuilt is NICE If you know the rebuilder!! As what one thinks is a rebuikd others will think something else, What is he rebuilding and is it right??

New is the way to go and for weight and all the other stuff Ibegoing with a new E Tec if I had my choice!

Sorry for lack of info .. Picts of my boat in my gallery. Its a 1978 20' welcraft with a 1987 150 fast strike .. Smokes like a Chimney. I replaced the fuel tank due to holes,, gasline,, fuel filter, tried differant oils.. spark plugs burn black ,, had it tuned up,, I dont trust the motor,, due to its a smoker,,, is it it ready to blow up ? ,, or is it just old and needs run .. It sat a long time before I baught it last year,, i didnt get much time on the water due to repairs, but it seems once I got all the gremlins out it was fairly faithful. Family would like to do some ocean fishing , but im not comfortable with the engine. I will try attaching a pict.

Are you running premix or injection? If premix, what ratio of oil to gas? What is the compression in the cylinders after the engine is warmed up?

I hate to break this to yeah, but that engine you have is probably the most reliable engine EVER built. The 150/175 EAGLE series as they were called are some tough engines that just don't die. If all is right with it you won't find a more reliable engine. Yes they are smoky and noisy, but when they are right the smoke isn't that bad and they run like a scalded dog.

I will have to invest in a compression tester,,, what should each cylinder be at warm temp ?

If you're still running teh VRO oil injection and getting alot of smoke, then you either have a bad VRO pump or an air leak in teh fuel line before the fuel pump. An air leak before the fuel pump will cause it to pump air with the fuel, and the fuel pump pumps in a metered amount of fuel for each stroke of teh fuel pump. If it is pumping air instead of fuel, then it will be pumping extra oil since there is no fuel to mix with it. Also when the fuel pump pumps air it will go from 100:1 which is the idle setting to the 50:1 which is the mid and upper setting. The fuel pump makes the change over based on how fast it pumps, and when it is pumping air it will go faster and pump EXTRA oil. Get the bugs worked out and chances are you'll have a good engine.
