Hello - I have been looking more seriously this year at repower options for our trawler and I'm curious if it's possible to repurpose a constant speed generator engine to propulsion?
Specifically a Deere 4045AFM85 constant speed at @121 KW which would be about 160hp.
If it's already configured as a marine genest (heat exchange cooling) would it take much to convert to variable speed? I can keep our current MG502 2.1 gears so it should mount up pretty easily.
As to the repower itself - we have a pair of 8.2's (225hp) that have been great. We love the boat and plan to keep her so I want to consider better options for long term maintenance over the next 10-15 years.
Already priced out Cummins Reman 210 6bt which would fit just fine and top out the budget, but also researching potential RTO of smaller common rail engines (4045, Volvo D4) as we would love to gain a bit more space in the engine room and possibly be bit quieter than the 6bt's. Mechanical Yanmar 4LHA could also be an option but may not be as smooth at hull speed from what I've read.
I would like to keep at least 150hp on each side - even though we'll cruise at hull speeds most of the time she will get up nicely at about 13 knots.
Thanks!
