Re: Replacing the Auxiliary

I found this for Yanmar marine engines (I couldn't find prices on Beta):

Engine model ~ Max power rating ~ Transmission ~ Gear ratio ~ List price
3YM20 ~ 22HP @3600RPM ~ KM2P-1A ~ 2.21 / 2.62 ~ $8,030.00
3YM20 ~ 22HP @3600RPM ~ KM2P-1A ~ 3.22 ~ $8,130.00
3YM20C ~ 22HP @3600RPM ~ SD20 ~ 2.64 ~ $10,600.00
3YM20M ~ 22HP @3600RPM ~ Bob-tail ~ N/A ~ $7,440.00
KM2P-1A transmission is a Yanmar mechanical cone clutch, vertical offset parallel drive.

Standard sales package:
To include marine transmission with reduction (except Bob-tail), flexible mounts, heat exchanger with coolant recovery reservoir, 2” water-cooled exhaust elbow (U-type), 12V starter with relay and 12V-60A alternator, digital B-type instrument panel with sensors, harness extension 6M, electric fuel stop solenoid, propeller shaft half coupling (except sail-drive and Bob-tail models), owner’s manual and tool kit.

Optional accessories (Prices applied only with factory engine orders)
D28890-49620 … Hot water tank adaptor fitting, 5/8” hose … $80.00
D28271-91570 … Wire harness extension 3M … $40.00
D28271-91590 … Wire harness extension 6M … $60.00


Not sure what the Bob-tail is. The sail drive would be out so it looks like the only choice would be what gear ratio would be needed. Anyway, it's $8K on the engine.

I could certainly disconnect things and open up the engine space enough to safely remove the engine. With a hoist and some help I could get the old engine out and the new one in. Outside of that, it would be either getting a qualified marine diesel mechanic in or reading an instruction book (no thanks). The engine would have to mounted at an angle because the shaft exits a bit off center.

So maybe I'd be looking at $10-12K installed?

I did hear from the broker. He said he'd have all the info for me tomorrow.
