The only other thing I was advised was to look into changing the gear box (and then prop) for a different ratio as she is still set for shrimping speed but I am really not in a hurry so 7 knots is fine for me...all in all, a good result.
As a guess the existing gear is 6-1 or 4.5-1 so the engine can get up on the HP curve and tow a couple of tons of nets.
The actual power required to power the boat , sans nets will be very much lower.
However the cost of a different gearbox and prop work would probably never be recovered with fuel savings.
IF the tranny blew , it might be time to contemplate a different gear ratio.
The electric will be fine , just remember when dockside playing with the DC stuff must be done with care behind the combined switch box..
My thinking exactly, if the trans gives up (goes west, south or anywhere it shouldnt LOL) then I might change it up, for now its fine....although when I used the prop calculator on the website the other Gent suggested it did give me a totally different number than whats currently on her. But, if it aint broke I won't be 'fixing' it...
