On this topic I researched this as an idea way back in the early posts, and realised after some research that there are several different types of spark erosion, but did wonder if this was a feasible method ? but since the bolts are so small I never followed it up .. so .. is it possible ? Cos I thought if the metals are dis-similar, maybe it wouldnt work?

A 1996 70hp motor would be worth putting right for the sake of a couple of hours labour (even a Twatsoo), provided it's otherwise in decent order and doesn't need any more spending on it.

Might I suggest that you get it to them now before your do anything else that might make it harder. .therefore more expensive.. for them to sort out for you?

What and kill this thread I think it could be padded to another 10 pages maybe even include an angle grinder to trim the bolts and re fix with Sikaflex

yes!

I disassembled everything which went well. I then drove around the isle of wight trying to find someone who would attempt to sort it out for me.

Lots of machine shops wouldn't touch it, were a very high price (25/bolt) or wanted me to completely disassemble the powerhead (I had the flywheel and head still on there). Spark erosion was either too expensive or it wouldn't fit in the tank.

Eventually I came across Lake Precision Engineering (not in Lake, in Fishbourne!) who have drilled and helicoiled it for only 120. I have not seen it yet but apparently they have done a really good job. I would highly recommend these people as they were the only ones that were keen to do it at a reasonable price and were willing to cope with the powerhead being only semi-disassembled. I will be using them again I think as they also do stainless fabrication.

Hoping to put it all back together today so I can get out on the water this weekend!

(oh, by the way, tried to use a blow torch and mole grips but had no success, the bolts were well stuck in there.)
