My throttle/gear shift...

Re: Volvo md7a overheating, temperature fluctuating

lol, yes. I did the fuel filters last weekend and was pretty shocked at the date written on the filter (it was either 05 or maybe 09 if the PO was european, though I don't think he was.) Was also...

Re: Volvo md7a overheating, temperature fluctuating

No idea (new to me boat). The fuel filter I took off the engine appears to have been there since 2005... Maybe the oil was last changed then too? In any case, it definitely needs to be done. Didn't...

Re: Volvo md7a overheating, temperature fluctuating

I don't think it's all that thin. It took me quite awhile to get a halfway decent picture of it, so I think that's contributing to that apperance in the photo. I didn't notice a fuel smell in the oil...

I did not do any sort of acid bath, just poked out the passages with a coat hanger. I'm thinking some sort of acid soak might be my next step. I just noticed a thread from about a month ago from a...

Re: Volvo md7a overheating, temperature fluctuating

Possible bad head gasket and no thermostat just masked that? There was no fluctuating with the old thermostat, just overheating at over 1500 rpm. Normal cruising is around 2000 rpm for reference.

Re: Volvo MD7A transmission water leak. Bypass?

Thanks for the replies. I did put some of that underwater epoxy stuff over the crack and it slowed the leak down to a slow drip. Should get me through this season. I'll keep an eye on the oil for...

Volvo MD7A transmission water leak. Bypass?

The housing of the transmission on my MD7A is cracked and leaking water. I was wondering if anyone has experience with running the transmission without water cooling? Terrible idea?

Not bad advice to take a boater safety course, but the OP is in LA and Texas does not require a boater safety course to operate a vessel (I am assuming the OP is over 18yo).
