Thanks Paul. I went ahead and shopped for the best price on OEM mercruiser risers and they shoudl get here within a week or so. I found a manual to download and unless I'm reading it wrong, the risers on this engine are also water cooled though I'm sure plenty of saltwater gets back up into the exists. The purchase survey recommended i lift the crossover tube slightly to prevent more saltwater getting in.

Hopefully I'll be able to give this a go before too long and without major problems that eat into the season too much. Scared to take it too far and risk water intrusion into the engine.
