I'm helping a friend fix up an old boat... I don't recall the hull manufacturer but it's a 14' fiberglass v hull from the mid-60s and currently has a 80hp Mercruiser (Renault engine) that's stuck and seems like it's going to difficult to find parts for. So, we're looking at the possibility of swapping in a complete new engine/drive, and have found a running 3.0L in a owner-abandoned boat (no title) that we're probably going to go check out within the next few days.
My question is, approximately how much does one of the 2.5/3.0L setups weigh? Also is there an appreciable difference in weight between the 2.5 and 3.0? Are these normally iron blocks? The Renault is aluminum with iron cylinder sleeves... haven't had it out so don't know what it weighs, but seemed pretty light.
He's concerned the 3.0L would be too heavy and/or too much power, so we're trying to determine if this is a viable option or if we should hold out to find a 2.5 (or other yet undiscovered options).
