The boat engine (outboard) is expensive because they need to withstand the marine environment well, so all the parts used in making one are expensive stuff. And they don’t sell numerous motors all the time, so to stay in business, they need to make a profit, so the price of an outboard (boat motor) is high.

It is essential because these motors must survive when submerged in the water.

Car/truck engines use a sleeve type bearing, but marine or at least the old ones used all roller bearings. There's is quite a large price difference in the base cost of the the bearings as well and the set machine set up for the rod caps and journals.

Been looking for a new boat as anyone seeing many of my old posts will see. Some of the boats we've looked at have had new engines fitted. Now, given the large cost of this, I was baffled why so many have been re-engined and yet still have petrol motors given the strong diesel bias of so...
Hekimian said ring sealing is an issue with marine engines, so he has his own custom ring sets made. The ring sets are expensive ($300 to $400 per set) but they solve a lot of problems. “With all the things we do to our engines, the engines will usually run 300 to 600 hours or go five to six years before they need any work.
