Title: Likely gearbox ratio TMD22?
Post by: blue-max on May 17 2016, 22:03

The plate on the gearbox is missing so no serial number or part number. Engine is TMD 22 75 hp, gearbox is type SM2 driving 35 mm shaft. I don't have prop size to hand. Anyone care to guess the likely ratio?

If it's a straight gearbox (ie no downward angle on the output shaft, it's probably 2.3 to 1. If it has a downward angle, it could be 2.4 or 3.0 to 1.

You should be able to identify the gearbox and look up the exact ratio on this sheet: http://www.volvopenta.com/SiteCollectionDocuments/Penta/Misc/drive_1_oil_rec_7745608.pdf

Unless I'm missing something, that sheet doesn't mention MS2 gearboxes at all. ???

Thanks for the chart - only just noticed. Still confused as VP agent tells me my engine has been mated with an angled drive 0nly mine is straight. Will send a photo for confirmation.
