Posting for a mate- he has a 12 month old 4 stroke 150 hp and wants to take it off the current hull and store it for 18 months or so while he gets a new hull built. He's found a buyer for the old hull which is a little deposit for the new one. Motor is still under warranty so will take to the installer to remove and box up. With both of us not being mechanically minded, I'm assuming storing for this decent period of time isn't a major concern? Anyone know of any concerns/risks of doing this or is this a pretty common practice?
