TAMD63P’s versus 370hp D6

[volvopaul]

Thanks Paul, and everyone else, for your comments. Very useful.

Sorry if this is a stupid question, but could a 63 be rebuilt in situ (with new liners) or is it a workshop job?

Depends on the boat, if it's a model with tank one side and not much in the centre then no on a twin , depends how high it can be lifted inside the boat, I've done many that way so nothing is impossible, I might be starting a Kad43 this week in situ, I'll let you know how it goes.

Rebuild of a 63p or any such engine is a workshop job.

The engines come out of the patio doors with A Hiab.

I'd disagree with that statement,that's what the dealers tell you.
RK rebuilt a TAMD75 inside a princess 45 mk2 a couple of years ago, as long as the sump can be removed once it's high enough it isn't a problem and can cut out many hours of grp work which I'm afraid is the case on a lot of sealines with drives.

Lol, my question was pure curiosity, absolutely zero relevance on my boat hunting!

In fact, my thought was that the cost of a full re-build or replacement block (including labour) is going to be £10k for the former and £15k (my guess) for the latter so not a great difference percentage wise. For VolvoPaul, the parts cost would be more significant as his labour would be free to himself. Make sense?

Nope, I'm relating the fact that the D6 is only available as a short motor should you blow the Pistons and bore .
The 63 can be rebuilt as it has wet liners and piston liner kit available along with the ability to grind the crank should it be seized up, you can't do that with the D6 and the parts are half that of the D6 short engine.
Labour cost doesn't come into the equation. It's a fact the D6 is going to be more to rebuild than the old engine.

Has anyone ever thought of a removable section of hull underneath the engine bay (preferably watertight - obvs). Then once the boat was lifted and on shore it would be possible to access below the crankshaft ?

In a boat engineers dream world that would be a fantastic option, sadly most of them don't even think about daily checks let alone how one can remove an impeller at sea or change a blocked filter on most boats under 40ft.

We had the job of sorting out a competitor in the round Britain powerboat race that did a DIY job and punched through the hull
Two engines lifted out hull glassed and back in for next morning
Owner tipped us as I recall about ten bob

Hi,

I´m looking for a next boat on 40ft range and one area I'm very keen on is the space in engineroom as I'm making normal yearly maintenance by myself. According to pics taken from engine rooms of Princess 38/40, I have feeling that they are the best compared to Fairline P38/30 or Sealine F37/42-5. At least the space I can see in front of the engines. Can you compare the engine rooms of these boat models in real life experience? Accessability to all filters and impellers etc?

Many thanks in advance.

Princess 38/40 all good part from starboard impeller and oil filters if it doesn't have the remote oil filter set up.
Phantom 38 the same.
Sealine F37 very good with KAD and D4( a client has mint F37 for sale) pm for details. KAD motor poor access to belts and front.
F42/5 poor access to starboard oil filters and impeller.
