What is this? It does not seem to be wired in on my boat. I am currently rewiring my engine and alternator and instrument panel. The question concerns a white and red wire that goes to the "rubber seal lamp (sail drive)".But down below in the engine compartment it is not connected I suspect it is an option not installed on my boat?

do you have a stuffing box on your prop shaft .......if yes you have no sail drive seal to worry about and the best i remember you have a full keel boat with a shaft going out the back of the keel..... so don't let that wire confuse you its of no importance at all ....you could use it for a high water alarm conductor if you would like and when the float switch activated the circuit it would set off the alarm and light up the light on your panel....you would just have to remember that its a high water alarm

Yanmar has a panel to fit multiple type of engine shaft configuration. It has a buzzer and alarm lights for oil pressure, temp alarm and sail drive seal alarm. With your boat, the sail drive is obviously not used and as suggested it can be used for something else so long as you remember what for. Not on the elctrical diagram, but the buzzer has 3 diodes built in connected to the oil pressure sender (yellow wire), temp sender (blue/white) and sail drive (red/white).

If you have an Island Packet the factory will bend over backwards to help you with problem solving, even if it is a modification or addition to the boat as long as it is a safe and realistic solution you seek. They were very helpful to us and we bought our boat used like most other IP owners.

You don't know if your boat has a direct drive shaft or a sail drive? Hmmm. The sail drive looks like someone mounted the lower unit of an outboard motor under your hull and not a shaft with conventional prop on it.
