Re: My first bow thruster service...

Hi Bill,

I'm also servicing my bow thruster for the first time. Wondering how yours went and whether you decided to use RTV everywhere? 

I'm also trying to figure out what the proper size is for the o-rings. Parts lists I've seen show 78 x 3 mm and 40 x 2.5 mm. Are the 78 and 40 the inner or outer diameters?

Also, any advice on where to find the 10mm neoprene seals? We're currently in the Fort Lauderdale area. Was thinking of getting a 10mm sheet and cutting seals from that.
