Re-power project.

Weather, working away and two weekend parties all conspired to keep me away from the boat. Progress resumed last weekend when I managed with the help of dad and a chum to get the tent up, electric and lighting today and made a start on a few things.

Here's what 480hp looks like in a Huntsman 28.

nice,

if you drop an M10 bolt (or nut even!) between the two motors will it reach the bilges or stay up somewhere??
Tight, innit? Can you properly service both engines in situ?

Are they ready now, or more work needed?

V.
 
The shafts are 28" apart, manual says minimum should be 27" but can be less if servicability is compromised.

Slight issue is the innermost rear mounts, no way of getting to the height adjuster nuts underneath, so I have some mods to do.
 
Dropping nuts and bolts is not bad while it is open as in Bens picture, a magnet on a stick can access most points. The only job I would really not want is to change a starter motor, fitted to the aft end starboard side and rather low down, but dropping the forward bulkhead (four screws) makes access to most things pretty easy.
Rear height adjustment is almost impossible either inside or outside, and I raised the back of the engines with a block and tackle repeatedly until I got the height right. It was tedious, but a consequence of the engine mount design, and would onlybe overcome by a complete redesign of the aft mounting. The block and tackle was, for me, and easier solution.
Another thing I did to improve general access at the aft end was to remove those cumbersome air cleaners, so I can actually see the gearboxes and heat exchangers.

Great to see them in Ben, afloat for Easter?

Yes, hopefully for Easter. In the process of rigging a chain block to lift them up. Thanks for those bits of paper.

I am guessing on about 36 knots flat out, and quite a lot of noise!
 
Successful sea trial this evening.

35.5 knot average in both directions on Southampton water, think we need more pitch on the props.

sticks forward at 25 knots is entertaining.

Woo hoo!
