I'm newly back to the boating scene having just bought a slightly used, but problematic runabout. I have a Volvo Penta 4.3 GXi-B, which you all know shares a heritage with the Mercury 4.3's and hundreds of thousands of GM trucks.
Given the above, I'm finding parts for the marine engines that look identical to the GM truck parts are three times the cost. I doubt they are "marinized" in any way other than possible slight differences that could impact performance. Maybe the MAP or throttle position sensors or the IAC sensors ARE tuned to require different voltages and produce different outputs. If the electrical characteristics are different, I can see why a relatively low production part would be much more expensive.
I don't know. Do you? Has anyone used GM truck parts such as the above on their marine engines? I'm just curious to know what the actual difference IS!
Thanks!
