Thats probably the hardest one to find, fitted to the P35.2.63:1
Chap from Germany drove over to collect my "spare" MS4B . E 1800.00.
Think the Corniches etc had the one of the other ratios, am aware of one of these........ in bits.

If all else fails do know of two boats which are running with a HS1 alongside a MS3 or 4.

How did they manage to use MS4 and HS1 on the same boat? the HS1 is a much larger bit of kit.
What was the original set up on these boats?

Both boats a Corniche and a P35 originally both had MS reverse gears installed from new.How did they manage to use MS4 and HS1 on the same boat? the HS1 is a much larger bit of kit.
What was the original set up on these boats?
AFAIK the physical dimensions and the output shaft down angle on the Volvo Penta HS1 and the MS 3/4/5 series reverse gears are indentical.
Its the added work to connect the hydraulics which are a faff. ?
It is the alternative boxes ( ZF 45 etc) which have different lengths and downshaft angles, which require jiggling the engine mount locations.
Very happy to be corrected.
One chap had a MS3/4 fail in a early Princess 33 flybridge with 165 Hp engines , DIY replaced both boxes with a pair of ZF 45 obtained from Lancing Marine who were doing a deal at the time, did not bother with repitching, sold the boat immediately afterwards.
Recently moored alongside a Corniche 31 purchased from new at a boatshow by a RCC club member,possibly now on its 10th owner ?????
Buyer from new had persistant problems with one of the MS gearboxes and eventually Volvo Penta gave up fitted a pair of brand new HS1 to make him go away. Gratis.
