    What Grease for '97 Volvo Penta Impeller?

    The last time I replaced my impeller, it came with a small amount of clear, silicone-like grease. I smeared the stuff around the housing and never again had the squeeling noise from the impeller when the boat was started. I remove my impeller every winter and would like to re-lube the impeller...

    97 VP Cobra SX Hit Rock - Whining Noise

    We hit a rock at low RPM, which destroyed the prop. I replaced the prop at the lake, and now have a loud whining noise above 1200rpm that's proportional to engine speed. In neutral, there is no noise, even at 3000rpm, which makes me think the lower unit is damaged. At home, I removed the prop...

    New '08 Chevy 1/2T; 3.73 or 4.10 gears?

    I'm about to replace my '98 F150 4x4 (4.6L/5spd/3.55) with a new 2008 Chevy 1/2T ext. cab 6.5' bed 4x4 with the 5.3L, tow package, camper mirrors and the 4.10 gears. I occasionally carry my 1250lb. pop-up truck camper and tow my 2800lb boat at the same time, for a GCW of 9800lb with passengers...

    Puffing from VP 3.0L Oil Filler Cap - Normal?

    Today I notice that if I remove the oil filler cap on my 3.0L (while idling), there's a fair amount of air pressure that comes from valve cover. I'm inclined to not worry about it since the engine runs good and delivers 4400rpm/35mph at WOT. Should I be concerned?

    What is purpose of the block-off plate between manifold/riser on VP 3.0L?

    Can anyone tell me the purpose of the metal plate (block-off plate?) that's sandwiched between the two silver gaskets between the manifold & riser on a '97 V/P 3.0L? Is the orientation of this plate important? I have the OEM service manuals, but the drawing detail isn't adequate to show the...

    97 VP 3.0 Blows Circulating Hose - NEW INFO

    This is a follow-on to my previous post about the circulating hose that blows on my '97 VP 3.0GS. While under warranty (and after blowing the 1st hose), the dealer installed a restrictor in the supply pump inlet hose. I've never been able to find information about this, the dealer went out of...

    What is the purpose of the shunt (for timing measurement)?

    I need to check the timing on my VP 3.0GS, and probably advance it for my altitude. I have the OEM manuals, and I've read them, but it's not clear to me what the shunt actually does. Another question, assuming I don't have the shunt, what would the timing be, roughly? Advanced or retarded...

    97 VP 3.0 Blows Circulating Hose

    I have a '97 Four Winns with a VP 3.0L. I've had the boat for 10 years and it has blown the large diameter circulating hose between the circulating pump and t-stat housing about 5 times. The first two hoses blew while under warranty, but the dealer couldn't figure it out; he just replaced the...

    Mysterious Metal O-ring in Cobra SX Gimbal Bearing

    I pulled the drive on my '97 Cobra SX drive to lube the gimbal bearing and u-joints. After greasing the gimbal bearing through the zerk on the side, I cleaned out the excess grease from the center of the bearing, and ended up with a round, flexible, metal O-ring on the grease rag. I can't find...
