Just a personal comment: I would never change a primitve dino like the ford lehman
with a new engine
. The 4JHtE is a very good choice but with the Lehman you run 8knots on 1800 rpm's. not sure if the Yanmar
would need 2500rpm's. Btw code's wrong, see:
4JH-TE5519851989at ENGINE MODEL CODES
Schematic's - I am quite sure that there have never been schematics delivered to the customers and Blue Water
Yachts is gone with the wind
What I would do and will do with mine is:
1.) try to get a BIG cable pit below deck
on the starboard side.
2.) try to insulate the batteries with big and logic +/- screw connectors
3.) start with engine
and charging electric
4.) Think about a generator
and and inverter
1500W (for a standard fridge)
light's and such
8.) 230V electric wiring.
distribute to starbord on top with a cable channel too.
try to remove every electric part from the bilge
If you got an engine room mount this parts
as high as possible - at least 2ft above the floor.
Never use cable-plugs use rings and crimp them on marine cables
(copper but each string tinned) Use shrink hoses to fully cover the crimped connections. Try to avoid soldering as the tin might be the wrong one and corrodes too.
