Yes after 14 long, long weeks, our boat is back in the water with a pair of diesels (no discussion of Red please)
With her bottom nice and clean and tweaking of the tabs and trim, the KAD32s pushed the Princess 286 at 20 knots at 2,500 revs, 25 knots at 3,000 revs and 30 knots at 3,400 revs. Props are A6. Top speed recorded in dead calm was (for us) a massive 38 knots. I expect that the log was a little out here but it was exciting.

We miss the hum of the V8's but miss them more at low speeds - between 6 knots and 12 knots the vibration progressively moves through all of the fittings on the boat. At one point the VHF arial was a sight with the tip staying exactly in position, but the arial itself desribing a perfect 'S' shape. We will spend the next couple of outings with sticky back rubber pieces placing them on hatches, canopy poles, plates, saucers etc.

Has anyone else experienced this and found a way to damp the vibrations?

Hi, Gotcha! Another P286 user with diesels! There were only about 9 fitted with 200hp diesels, and although yours was converted I am glad to make your aquaintance.

Have AQAD 41As in ours, we do not get plates etc rattling at all. The volvos are very smooth. I certainly do get this effect on the old Fairey, fitted with Fords, but only at 600-900rpm , after that it all smooths out.

Engine vibrations are sometimes transmitted through the hull because the mounts are not doing their job right, or by something on the motors touching the hull directly, or even being bolted down so hard any rubber mounts are crushed to hell. Feel free to pm me for locations and stuff, if I can be of any help I will.

Phil for info, one of the girls that works for me has just bought a 286 with twin volvo 200 diesles, they picked it up from Hamble point yesterday and brought it back to their mooring at Itchen marine, it is called On a Mission.
