I didn't provide any advice! I made an observation that until someone more knowledgeable demonstrated otherwise I would always assume that catastrophic destructive gearbox failure may have been caused by collision with an underwater obstruction

Apologies if the word prove was too strong.

Andy, I had seen that motor. I'm way down the merc/mariner line at the moment with spares, workshop books, props etc. It does have me thinking though........ Flippin huge motor though eh?

May have had a stroke of luck for the moment - the old Mariner 150 efi which came off this boat won't release it's leg to me but I expect it will let me have the gearbox easy enuff. Gregg at GB watersports has suggested that I can use the leg extension on its way from Madrid and discard the extension shafts. Then the gearbox off the Mariner c/w shafts should go right on! Jeez I hope so!

I'll keep ya all posted. Thanx again folks!
I've just pulled that Honda 225 in and it's huge indeed!!!

"Please don't hit it - that's "unreasonable"". Of course I was joking........ I think I've made my position on this fairly clear haven't I?

Update - it looks like 2 or 3 probable causes behind this now. The bolt at the very rear of the lower casing which shoots through from under the trim plate was completely missing which wasn't a very good start. 2 of the remaining nuts holding the lower were loose (one had unwound itself by 2 threads already). The additional stress caused by fitting the rather large planing plate probably took advantage of this and exploited the weakness and then I assume the stress placed on the gear set that resulted finally took its' toll.

RIP merc gearbox.

Fortunately I had a spare on my buggered 150 EFI now fitted. We had to helicoil a thread in the mid where the missing bolt was as that appears to be the reason they didn't fit one (no thread there at all).

Fingers firmly crossed now.
