New style down pipe 'should' bolt straight onto the old style transom housing.... But, you'll need to pull the engine to do it.
That's what I thought too - but the pre-alpha transom plate blocks the down pipe from fitting. The pre-alpha has the engine mount holes further apart than the later Alpha 1 style, so the support gussets on the transom plate itself are in a different spot - the down pipe hits the transom plate and won't sit flush against the transom housing
So, I either need to cut the transom plate (not happening), or use the pre-alpha downpipe. But that downpipe doesn't line up with the new-style riser on the motor. Which means I guess I need to use the pre-alpha style riser as well. But THAT doesn't bolt onto the new style exhaust manifold...so I suppose that's being swapped out too.
I considered buying an alpha-1 transom plate instead, to replace my pre-alpha. That would make it so much easier - exhaust would bolt on, and I wouldn't have to swap out for a smaller flywheel on my new motor either. But I don't know if my existing cable steering would bolt onto the Alpha 1 transom plate? Looks like it mounts differently than mine.
