Lucas engine oil leak fix

[SCOOBY151]

hi there,
I need a little help. Yesterday I took my boat out for the first time this year. When I switched the batteries off , I noticed quite alot of oil in the bilge. I traced it as coming from the sump gasket seal. I lost about 1 ltr of oil for a 1hr cruise. Since I just put the boat in the water, I don't really want to take it back up. I am looking at all possible solutions, one being the Lucas engine oil stop leak additive, anyone have any direct experience with the product? Do you think it would temporarily solve my problem? At least for this summer?
Any feedback appreciated, thanks

by the way, the engine is a mercruiser 4.3lt from a 1993 2700 SCR

well...I'd think you need to pinpoint the location of the leak better...if it's just the seal of the oil pan...then I'd look at trying to tighten the oil pan bolts to make it seal better....if that's not possible...I would look at pulling the boat and engine out to replace the oil pan gasket.....

would I use that lucas stop leak....no...I wouldn't use it...remember if it's going to stop the leak..it's going to stop the oil flow inside the engine on small ports...which will or can cause internal damage from no oil flow....

since it's a V6..it shouldn't be a big deal to pull the engine...that will allow you to clean the bilge and do some interior painting and even some bigle pump mods....

sorry but this isn't an easy fix per se...but it is the right way to repair the leak..

What SP said.

If the engine really lost 1 Ltr of oil in 1 hour that is quite a lot. Are you certain it came from the sump (oil pan)?

One thing you might be able to do is add a dye to the oil. The dye will glow under a black light and will help you or the mechanic find the leak.
