Thank you all, I established that it is a 506 transmission so I'll use 30 Wgt.

You are right: it is a 506 - I'll go with your recommendation (ie: 30 Wgt - I am in Northern California with mild winders and cold (but not freezing) waters) - any specific brand you recommend?

Thank you. I did not see this info on the gear, but I'll check again.

thank you. Ill check the model next time I am on the boat.

Thank you, yes on getting the leak fixed but mechanics are slow and backed up in my neck of the woods. I will check the transmission model next time I am on the boat and post more details.
