Since these engines are raw water cooled, meaning no heat exchanger where a closed circuit of coolant is used, the raw seawater circulates within the engine. Corrosion could exist in an area that has compromised the engine block.<br />
It could be as simple as milling the head if the corrsion exists around the head gasekts, which is the most common area for oil/seawater exhange to occur.<br />
Need to check the tollerances on milling as this would increase your compression slightly.<br />
Good luck.

If you have any mechanical abilities, do it yourself. That engine is small, not extremely heavy and very simple. If unable to do it yourself, order the parts and find a tractor repair facility near you. Iowa should have plenty of these places, and a diesel is a diesel is a diesel.

Gary, I just finished a rebuild on my YSM 12 which is very similiar to your engine. I am just a shade tree mechanic sailor. The most difficult part was getting the tool for pulling the cylinder liner. I had a local machine shop build one for me. With the tool, removing the liner is easy. Installing the new liner is easy also. In my rebuild I replaced the head, the liner, piston and rings, and rod bearings. I did not tear the engine down far enough to change the main bearings. I did the work…
Gary, I just finished a rebuild on my YSM 12 which is very similiar to your engine. I am just a shade tree mechanic sailor. The most difficult part was getting the tool for pulling the cylinder liner. I had a local machine shop build one for me. With the tool, removing the liner is easy. Installing the new liner is easy also. In my rebuild I replaced the head, the liner, piston and rings, and rod bearings. I did not tear the engine down far enough to change the main bearings. I did the work with the engine in place in the boat. These old engines are well built but have a couple of design problems. The heads are bad about cracking between the intake and exhaust valves. The oil pump has a bushing that can result in a low oil pressure problem. I have not tested my oil pressure with a gauge yet.

Thank you Claude, I am sure that wil be helpful.....Following Lolas' advice, I have located small qualified, shop nearby that will give advice, has equipment, and will let me do as much as I can, Asks $40 per hour for his time.<br />
With parts from Torrenson, and your manual, Should be ready to get to work after Christmas....Thanks again.....

Just my opinion,<br />
But I feel that Lola was overcharged about $5000.00. It's criminal when a shop charges based on the knowledge base of the customer. Lola could have bought a new engine and had it installed for a few dollars more.<br />
