We replace our Oil Sending Unit, added a Fuel Filter, replace our alternator, and rig up a PVC pipe on our 2004 Bayliner Bowrider 175. We know we have good oil pressure because we have an oil pressure test kit that verified it on this boat. We did take the boat out using only the oil pressure test kit out on the water but found it leaked a little oil after running for a while.
While our old oil pressure sending unit on our boat was very rusty this did not worry me. What did worry me was that at idle it would not tell us we had pressure, at RPM it would bounce between 0 and 40 psi. After installing the new oil pressure sending unit we did return oil pressure to our gauge.
While we were looking over the Mercruiser 3.0 engine and making sure things were all tight we saw we didn’t have a fuel filter. We have not rebuilt the carburetor on this engine and really don’t want to if not needed. May have to get a larger fuel filter later, this one was a little small for our fuel line, and when we install a metal fuel line we will move the fuel filter closer to the gas tank on our boat.
Replaced or alternator on this old boat, and the new one fit perfectly supplied us with 13 volts on the dash and was half the cost of the OEM alternator. Not really that much else to say about our new boat alternator on our Bayliner Bowrider 175 except it worked.
Lastly, we put on PVC hose running to our breather, yes we know the hose we use isn’t ideal, but we will replace it. This will keep oil from leaking on top of our valve cover until we get the proper hose.
