Thanks for the info
Thought they we roll pins don't seem to want to come out the sud had been replace with a steel bolt in the past before I owned it it has broke flush with the gland face I tried to drill out after removing strainer but drill broke as it broke though you can imagine the air at the time so only option is to remove the hole stern gland to take to a machine shop to remove it might then need a helicoil fitting I will have another go at the pins

Plenty of heat and put a block of wood between clamp and hull otherwise flexy joint could absorb some of shock.
Did pre soak mine with penetrating oil, did not do much.Those roll pins cost pennies.
Need to use proper drifts other wise you might expand pin and make it harder to shift, ask me how I know.

As oldgit says.

Block of wood between clamp and hull, heat, correctly sized drifts and a lump hammer. You won’t be tickling those roll pins, they need a good belt.

I’ve done both mine on 1 3/4” shafts and the same style clamps - it’s not pretty, but they will come out.

Bad luck on the drill - I can imagine your frustration!!

When trying to undo one of the rotten stbd, outbd fwd mount studs I insisted we immediately leave the boat at one point (wife was with me) as if we hadn’t, I was likely to take the hammer to the engine! Came back the next day having calmed down a bit..

Nightmare of a job on the corniche access in that area is poor, I had the same fight last year.

I can now officially agree. They are in but that was a loooooong fight. 30 year old bolts gave a good fight.

I am now faced with another dilemma. The engine bearers are drilled for M10 bolts but the mounts have 12 mm holes. I am thinking that 12 mm od threaded connectors could be cut to take up the gap. No way is a drill going down there.

Thoughts?
