Under water'd engine..

[dompie99]

OK.<br /><br />I just opened an 150 mariner eng. that ( not told to me ) was left under water for a while. The crankshaft is pitted ( stripes perpendicular to main and rod journals ''3'')<br /><br />How far will it still be recoverable before having to get it remachined to standard spec's<br /><br />I measured the rod journal ( the worst one and it's still at 1.185'' with the pitting marks.<br /><br />I ordered main bearings, rod bearings upper and lower bearings (new).<br /><br />I won't fool the customer for 800$ CDN i can get a rebuilt crank with a 100$ for the Core.<br /><br />Thanks in advance.<br /><br />

If the brg surfaces won't clean with 320 paper it won't last long

HI,<br /><br />OK i read about this issue a few places around but fi i remove the «' tinny groves .001 in.» what is the minumum diam of the journal that is acceptable. <br /><br />As i stated, i have 1.185 before any mod to the crank.<br /><br />Jacko

DO NOT take this as a recommondation, but we have cleaned .001 to .0015 off new crankshafts on our 44 cu. in. class D racing engines to loosen them up, however these engines are ran 24 to 1 and not run on a daily basis

HI Laddies,<br /><br />Thanks for the suggestion,<br /><br />I checked the '' UNtouched rod bore'' and the rignt measurement is 1.181 not touched nor sanded or else.<br /><br /><br />I '' cleaned'' the worst one to find-out that it got down to 1.180 with a possible out of round of .001 max......would you think that this is acceptable for a rever ( 7,000 rpm )<br /><br />Jacko

Try it.......... worst you can really do is blow up a motor that might well have been dead anyway. <br /><br />-W

It will run OK, just do not know how many hours it will last before "Shaking itself" to death.... after a few hundred hours, I would bet you will have to go in again.
