The service kit comes with an impeller, that would suggest they expect it to be changed annually with the filters. The impeller is a Jabsco one, presumably they make the pumps forVP.

Good luck.

The heat exchangers are supposed to be removed, cleaned and re sealed something like every five years. I will need to do this to mine soon but haven't found out much about how to do it. Other than quite a lot of stuff needs to come off. Is the impeller ok? Any growth in the water intake?

Another vote for the forward seating area, for me a must have feature.

Yes you can. Flush through with fresh water then antifreeze as per the manual.

Get a non contact tacho, measure engine and shaft speeds, divide to get ratio.

I believe at one time we had military engineers and civil (short for civilian I assume) engineers.

Do they have the same thin mild steel rust prone sumps as the D6?

If you are running a Seaward it is worth getting the consumption curves from Seaward. The 25 is as economical at 17kn as 10kn.

With a bit of platform each side of the outboards could you use extended snap davits to move the tender clear of the outboards?

Liters | Mercury - Evinrude - Yamaha - Suzuki - Honda - Tohatsu - Outboard Fuel Consumption per Hour LPH

If you want to do away with outdrives maybe a single rather than twin shafts using one of your engines with the other for spares is the way to go?

If you are going down the different oil route I have found Millers to be very helpful. And good products. My previous boat had Ford D6 engines, they seemed to use and lose less oil when I switched to Millers. Still a smokescreen on cold starting though.

Is there a breather built into the oil filler cap? How much comes out if you take the filler cap off when running?

Alternatively just go out and enjoy a proper boat!
