Hi Guys,
Really appreciate any help you can offer in advance. I have no practical mechanical knowledge and 2 small kids that cant swim.
Ive found a 45 Foot boat I want to purchase that has 2 x 1971 Detroit 8v53 285Hp Engines.
These are my concerns;
1) They look in good condition (Fresh paint all over) and Ive told have been rebuilt in last 10 years but have no proof.
2) havent been used much for the last few years
3) Went for a sea-trial yesterday and boat put out a fair bit of whitetish smoke under load mainly (Boat Broker told me its normal for not being used for awhile)
4) Had oil change in last 6 months and hardly been used.
5) I want to get an oil sample analysis (expensive) but my concern is engines havent really been used since Oil change.
Questions;
1) Is it still worth taking it for a half hour run and then getting an oil sample analysis ?
2) Anything else thats really important to check for ?
Side note:
When we did sea-trial one engine made a loud pop, tonnes of smoke and sea-water stopped coming from one exhaust. At the time we were WOT
and hauling at 18 knots. (45 foot boat).
We limped back on one engine and Im being told its being repaired shortly to determine fault. Most likely just impellor I was told.
Please I welcome all thoughts ?>
Cheers,
Lee
