However, be prepared for the higher cost of ownership and the occasional noise.
Recommendation:Before making a decision, it is recommended to research the specific model of 5.9 Cummins engine you are considering, as well as the availability and cost of parts for that model. Additionally, consider the specific marine application and your personal preferences to determine if the benefits of the 5.9 Cummins engine outweigh its drawbacks for your particular situation.
The rear of the block, 6 cylinder, has the improved water outlet for cooling. It is complete and in running condition. I ended up buying a diesel powered tiara and no longer need these project engines.
The engine wiring harness is plug compatible with mercury and crusader. A transmission oil cooler and bracket is include but not shown. The engine has been run approximately 2 hours on a water brake Dino per Cummins break in procedure for the first 3 steps, to 75 power. My hoist will load into a pickup or on to a car trailer.
No transmission is included but does have a transmission adapter plate, suitable for velvet drive or hurt. Exhaust boiled out and pressure checked.
The engine was originally built in 1991 and has the small 7mm injectors. New hoses and clamps were used in assembly. 9 m Marine diesel engine this offer is for 1 naturally aspired 115 hp in line 6 cylinder diesel. It is heat exchange cooled and has the low profile aluminum oil pan.
The Dino is designed for higher rpm horse power so I was unable to get to the 100 load at 2500 rpm for the final step. Cummins 6b5. The engine has gone through reconditioning that includes block stripped and phosphate treated, new pistons, rings, bearings, head resurfaced with valves and seats ground, valve springs tested and replaced as needed, rocker arms bushings checked, rebuilt injectors new nozzles and pump, new 12v starter and 140a alternator, rewired to include new temp sender and separate alarm, new oil pressure sender and separate alarm. Why am I selling I bought the engines in unknown condition as USCG takeouts.
They needed much work and conversion to 12v as outlined above. I do like the 2 GP fuel burn though. Heat exchange and oil cooler cleaned and pressure tested.
I cannot lift into a semi. The parts were primed and painted prior to assembly. I have already converted a tiara to Perkins 4. I am retired and not in any hurry while cruising.
I have a second matching engine available separately with the only difference being a 105a alternator. My original intent was to buy a gas powered tiara and re power with these diesels.
