Do the engines keep the closed circuit cooling system as they use when installed in a land vehicle? No electronic ignition system to worry about, what a blessing and piece of mind.!
How is the automotive block able to handle the continuous heavier marine loading, when the automotive blocks typically see 2000 rpm at less than 25% throttle at cruise? What is the expected block and top end rating longevity in hours before total overhaul?
Much like regular commercial operations, it's not the RPM that's the issue, it's the continuous change in operation that becomes an issue. I seriously doubt it's loaded any worse than it would be on land, but the bonus is you set the RPM and leave it there until you reach destination. The engine systems have a much easier time finding equilibrium like that than they do when the power requirement is all over the map. It's like highway use vs stop and go traffic, same thing.
@@viasevenvai Absolutely not. Highway operation is nearly steady state operation, constant speed, temperature and load... city driving is start and stop, short trips, inconsistent loads, temperatures, and speeds, everything even the brakes are working more. You shouldn't have to be an engineer to understand why not messing with something is better than constantly fucking with it.
The BMW production 4 cylinder block (gasoline) was used in their F1 turbo engine and was delivering on the dyno 1500hp. Now of course I'm not saying it will last for years but just to give an indication of what some blocks can do. It was used successfully on the Brabham, probably the best looking F1 car ever by South African Gordon Murray.
Not necessarily, a lot of motorcycles are belt drive and last the life of the bike. Timing belts are meant to last close to or over 100k. Belt drives have come a long way so don't knock it until you try it.
I ran a stump grinding machine for 8 years straight all the time and sold it with the original belts that it came with to another guy I made hundreds and hundreds and hundreds of thousands of dollars with it while I had it the guy who has it now still runs it with the same belts 2 years later
