Repowering with a Naturally-Aspirated Engine

[wizz]

My 15T 43ft steel ketch had a Perkins 4-108 engine that has seen it all at 5000hrs. I am considering an upgrade to a 60hp engine (2hp per 500kg). Has anyone anything to say about a Mini-75 Solé ? It is a spanish commercial marinisation on a Mitsubishi base (max output of 65hp at 2500rpm). Here in the med it is considered best price/value ratio. What about its presence elsewhere in the world? See www.solediesel.com
Thank you for your opinion

My experience suggests that the SM-105 may be better suited if you have the space, the engine bearers can take the weight, the prop shaft can take the torque, there is space for a larger propeller and you can fit a larger exhaust.

Hi - is it sold with or without gearbox ? Do you have a price in dollars ?

Approx 7800 U$ with a mechanical gearbox.
The SM 105 will not fit through the cockpit and seems indeed to be overdone power wise also bcse my shaft is 1" 3/8 and the propeller cage will not fit anything more than a 19" prop.

Since the marinisation part of the engine is usually more prone to failures, which spare parts are essential to keep on board?

Ouch..You wore out your 4-108 in 5,000 hours?

What RPM did you run it and what prop size and boat speed?

Other folks get 10,000 to 15,000 hours from the 4-108s. Bullet proof engine.

5,000 hours isn't much in the scheme of things....unless it has been poorly maintained by a PO

Running rpm 1800-2000, prop 16"x9", speed 4.2-4.7 kn.
