625 HP all natural oil pressure problem
 

Terry please check your mail
Thanks

We loose oil but we do not see any oil leak. So we think it is the oilcooler that is broken.When we top it with oil pressure is ok but after few minutes oil pressure drop dramitically and oil has disappaered. So if anyone knows answer please let know. Thanks

do you see a sheen of oil on the water?

Is it in the bilge?

there is no oil in the bilge and we see some oil comming from exhaust

any obstruction would give high oil pressure but we have oil pressure drop. As long as oil pan had oil in it, the pressure was ok. After few minutes when oil in pan gets empty we see oil pressure drop. I f we check oil level after oil pressure drop, there is almost no oil on dipstick (to control oil level)

Terry,what oil cooler is on this engine so i can order a new one. I want to get the boat out for a ride.

When I did test ride with M.Allweiss the warning sign also went on but stopped after a while. He said it was due to some water that was on the sensor... But when the boat arrived in my factory there was a big can of oil under the back seat...

As if I can see lots of oil on the water no I don't. But the oil is new and clean so you see not so easy.But at my dock there was a film on the water

Terry,

Thanks for quick reply and help.
