Merc 6.2 ????????
 

i was out running around yesterday for about 3 hours, we were in smooth water and only cruising about 3500-3900 rpm's. we had stopped and idled for a while then took back off, about 10 min later i hear what sounds like i just scattered a motor, these are bone stock with about 300 hours on them, i had good oil pressure and the temp was fine.

has anyone heard of this before? i was wondering if this maybe a one time thing or if it is common on this motor.

i shut it down as soon as i heard it, when i opened the hatch there was nothing out of place, so i turned the key so i could listen to it, it started right up but sounded like there was loose gravel in the head...

Ouch. I'd first pull the valve covers, and drain the oil/ inspect the filter. Could be a lot of things up top. If it did break something in the top end, you dont want to run the oil with debris in it. Keep us posted.


Darrell.

we are pulling them tonight, i'll post up what we find..

Did you see this thread?

well i feel kind of stupid and some relief at the same time, i had the marine mecganic listen to it before we started removing things and it turns out tht it's not the engine at all, the outdrive is blown. it's a sound i've never heard before and one i'll never forget... so now i need to buy a drive

U-joints or gears?? Steve

Sorry for your problem. I assume you have Bravo's. Kind of unusual to pop a Bravo with a small block. Might want to try and figure out why.

If that is a 1.65 ratio I have some at a good price.

gears

1.5, let me know
