I've been on this train for a long time as well / engine, gen-set, rudder, trim tabs, prop nut & bow thruster . Ordered my zincs from them at the Boston Boat Show this year. Having a couple of thruster zincs in reserve my order totaled about $ 85.00 / $ 15 short of the $ 100 minimum to receive free shipping. The owner said close enough for free shipping for a loyal customer as he pulled my previous orders up on his laptop. They arrived in one day via UPS.
A few years back at the show I said how it sure would be nice if the thruster zinc included a new stainless steel prop nut. They thought that was a good idea too and low and behold; future thruster zincs had ss prop nuts in the packaging.

There's a company that showed that they care about customer relationships and actually consider ideas that hit the suggestion box. Very nice.
Fantastic pricing as well!
