I am with Bob on this one. Your insurers will take any opportunity to hike your premiums or simply not pay out. It’s not a big job honestly. I have done one on a 32 its about 15 hours work. So doable in a weekend. You need to get your prep all done first like marking up the engine controls and cables which is about 2 hours work. I would say if you have not done one before it may seem a bit daunting sliding the engine forward and pulling the leg up into the boat, but if you do it step by step and follow the process…. I will be doing mine on Impavidus in 4 years time, I will do it myself over a weekend. Bob or myself, or some other club members can talk you through it. If your local I can probably lend a hand for a bottle of Blue Sapphire 🙂
