Replace marine head with composting head


I have never liked marine heads.

I'm going to replace my marine head with a Natures Head. Has anyone done that? If so what problems did you encounter? I plan to plug off the hoses and just leave the tank in place at this time in case some later owner actually likes a marine head.

Thanks Steve

Depth sounder "in hull" installation


My present depth sounder a Datamarine LX 200 ( original ) wants / needs some rest. It is reading are all over the place, for sure not the water depth. As I'm not planning to haul for now, I'm thinking about an "in hull" instead of a through hull transducer installation.

Question now is where?

Anybody done so with good results and where in the hull?

I have a Sundowner Tug 30 serial number 115

Looking forward to your advice suggestion and or comments.

GHP 10 Autopilot installation

Hi everyone,

This year I am getting ready to install a Garmin GHP 10 autopilot onto my SD30. My current manual hydraulic steering is the standard Wagner Steering, fed by copper hydraulic lines. I have a few questions.

1.) The GHP 10 requires a hydraulic pump be purchased separately. Your options are either a 1.2 L pump that is recommended for a steering cylinder less than 10 cubic inches. 10 cubic inches seems rather large and I'm pretty sure the 1.2 L pump will work just fine, but I wanted to see what size pumps some of you all are using out on the water?

2.) I need to know if my current wagner steering is balanced or unbalanced. The Garmin website states...

Has anybody ever done this technique with a Sundowner Tug to paint the bottom without taking it out of the water? The boat is in Whittier, AK, where it's very expensive to have it hauled out to paint. Any suggestions or advice appreciated if you've used this - did you brace it, let it sit on one side at a time?

Window Sealing

Does anybody have information on sealing/re-bedding the cabin windows? I have used several of the so called urethane sealers to stop water leaks but I want to eventually remove all the windows and re-seal them.

3M 590 is recommended for glass installation for marine, auto, etc. Has anyone used this?

Emerald Lady for sale

My Tug a 30ft Sundowner is for sale, I have owned it since 1982 as the only owner. It is at Banana Belt Boats in Anacortes Wa. I have bought another boat, otherwise I would never sell Emerald Lady as it has been a wonderful boat.

Boat Insurance

My insurance carrier BOAT/US refuses to increase the valuation of my 1985 Sundowner 30 from what I bought it for in 1991. I am currently having the entire boat Awlgriped for big bucks. It should end up being worth upwards of $70,000. Boat/US uses the Buc book for used boat values which states that my boat's value is around $36,000. Has anyone else run into this problem?

Propeller for 30' Sundowner Tug

I have a 30' Sundowner Tug with a 100hp Yanmar diesel engine (4JH4TX1) at 3200rpm. She has a 2.04 gear reduction.

I am looking for someone who has had experience with a similar tug, rpm and hp and what they are using for a propeller size.
