Repowering a Grand Banks YachtWe have repowered many Grand Banks yachts here in the yard. The engine removal is just part of the total picture however. While you have the engines out, it is a perfect opportunity to do some cleaning and repairs that are not possible with the engines in place. Below is the usual chain of events when we swap out engines in a boat.
- Shut off all necessary seacocks, cap off fuel connections, etc.
- Strip all parts from the engines, including disconnecting all wiring and fuel connections. This would include all parts on the engine that can be removed – we need to slim this down to fit it through the window.
- Lift engine off mounts and up into the cabin
- Lay sideways on a sliding platform that extends out through the window and roll out the window for removal from boat
- Effect all cosmetic and repair work behind where the engines were previously mounted.
- Check condition of stuffing boxes, couplings and mounts.
- Strip new engine down to fit through window.
- Lift to rolling platform and reverse procedure for getting engine out.
- Reassemble engine and hook up all fuel, exhaust and water systems. *
Before beginning, the whole cabin was papered and scrap carpet was put down to protect the sole. There are planks temporarily covering the engine access, but you can see that the engine pan has been removed and is being repaired and thoroughly cleaned.
