Dive Service Recommendations - Lake Union Area

[Splash]

Hello from a new owner (2015 R-27 "Splash") delivered October 30th. I'm looking for recommendations for a dive service, primarily to inspect and change zincs. Any help would be most appreciated as would a rough idea of the cost of such a service.

My wife and I look forward to meeting many of you in the coming months, years............thanks in advance.

I strongly recommend...

Double J Diving
5713 Hillpointe Circle
Lynnwood, Washington 98037
(206) 282-7900

I have employed them for over 3 years and their service is EXCELLENT. They will provide you with underwater photos of the anode condition before and after replacement.

After a few services they will establish a proper schedule to check the underwater anodes for you. This can vary as water conditions change at your dock and with other boats docking close to you over time.

They also check the bottom paint condition, scrub crud off the trim tabs and perform light scrubbing on the prop and rudder with the Marina's policies for underwater cleaning.

It always helps to have the rudder full over to port or starboard for easier access to the prop shaft anode. This is the one anode that erodes the fastest on our R-25.

I highly recommend this Double J Diving company. It's operated by a Husband (Jorge the diver) and Wife (Janel)

Here are my chronological cost numbers for past year or so

...and here's a typical breakdown of a service cost

I hope this helps you with your decision. 🙂

I use Emerald City Diving in Seattle and have been satisfied with their service.

Splash: One thing you should enquire about is the use of Aluminum vs. Zinc material for your underwater anodes. My Double J Diver service switched over to aluminium about 2 years ago for my boat, and they do seem to last a bit longer. However, as I said, water conditions will change over time affecting the anode erosion rate as well as boats moored/docked near by that come and go.

Keeping a close look at the underwater anodes is very important IMO. Leaving the anodes without periodic inspection is a recipe for disaster and will lead to expensive repairs if the anodes erode completely.

The anodes will erode if they are doing their job properly.

You might give some consideration to installing a Galvanic Isolator (GI) to avoid stray current from the shore power. They cost around $200 so keep that in mind.

On my R-25 in addition to the stock anodes, I've installed a GI, a prop shaft brush, installed donut anodes at the base of each swim step brace and a transom anode connected to the engine ground/bond system.

Thanks for the help folks. I did get the GI from the factory and am augmenting with an aluminum grouper zinc, but will either have the boat checked with a dive service (or hauled) a regularly. Again thanks for the quick and thorough responses.

Or get a hooka diving system and do it yourself.
