    Battery Switch / Corrosion prevenitive?

    WillyBWright are you saying, and it does seem to make sense, that a batt switch will reduce corrosion in the engine bay area. The reason I ask is that I was given one new in the package but have never had problems with the battery running low so I never installed it, will it cut down on...

    Did you Say 30W?

    I was reading an early post and noticed that someone said to use 30W engine oil for the lower unit for a Volvo outdrive. My manual tells me to use gear oil rather than engine oil, of course my manual if for a 1992 290DP. Should i be using 30W engine oil or stick to the gear lube? "Volvo now...

What if anything do you guys know about this? This...

Anyways sometimes I don’t have to mess with the...

    Impeller Question

    Hello All,<br /><br />I recently replaced the water pump on my 1992 431A Volvo Penta. So all is good, right? The question: "Is there an additional water pump or some other type of device in my lower unit that I need to keep my eye on?" My mercruiser buddy tells me that there is also an...

    Hello all,<br /><br />I am getting a knocking noise on my 19' 1992 stingray runabout with a 431A Volvo Penta DP290. I know the knocking is coming from the lower unit. Not sure of the specific nomenclature so I will speak my terms. With the lower unit trimmed all the way up it knocks when...

    Soaking Prop rather than cutting?

    I had inquired earlier about cutting off my FWD Prop from my Volvo Penta 290DP-C1. A person in my shop, Marine Corps Shop, not marine Shop, mentioned that for engine block and the likes that are corroded that he does not want to cut on or heat up he would soak them in diesel fuel, kerosene...
