Allthewaythere- I have a 45.2 in the SF Bay and have been looking into a bow thruster. Do you mind sharing all the details of yours and if you would do something else if you did it over again. I am interested in everything. What kind and what brand you have and where it is mounted. Where you put the batteries. If it takes up too much room in the forward sail locker etc. How far forward is it mounted. Also where and how you got it done. How does it preform in big wind? I feel like the 45.2 has a large amount of windage and in the bay that makes it tough to get into quite a few spots. Thanks

I had problems with the thruster on my 2009 42DS a couple of years after purchase. I thought power had dropped off slightly but battery voltage was OK. Then performance became very poor and the battery wasn't charging properly.
I tracked to problem down pretty quickly once the battery wasn't charging. I had examined and cleaned all the red/green screws on battery connectors each spring and never spotted a problem. The problem lay inside the clamp connections on the battery posts. They were black and badly pitted on the inside. The posts and/or clamps weren't cleaned when first assembled and had been arcing inside ever since. Nothing visible from the outside and voltage on charge looked OK if touching the clamps. Voltage was low when charging off so battery wasn't accepting the charge (as current getting past the clamp was minute).
I replaced the clamps, cleaned them and the posts, smeared a little Contralube 770 and re-assembled. The improvement was dramatic and better than I'd ever remembered. It has been fine ever since.
I rarely need to use the bow thruster and try to remember to give it a short burst a few times each season to throw off some of the growth. However, it usually stays reasonably clean.
One tip: You are meant to put some silicone grease on the shaft each year and I didn't spot that for a couple of years. Now I simply remove the props after hauling out and cover with some tape over winter. Much easier to anti-foul tunnel and props before reassembly in Spring. Simple to smear a little silicone grease over the seals before putting the props back in place. Really easy to remove the props., pull the fuse to be safe and unscrew an allen bolt on each side. Dig out old anti-foul or growth first with a pin or allen key won't go in far enough to grip.
