@ttmott can you also show me your booster pump install.

Pump on the left is the booster pump and the one on the right is the bridge AC. Three-way valve selects one or the other from a common strainer and thru-hull.

ok can you run both pumps at the same time? Is there enough flow to make that happen?

The valve is one or the other; not both.
I don't think it would work as there would be no way to start the pumps simultaneously.

@ttmott What are your thoughts about "y" piping it off of an engine strainer since it is much bigger. I would never be making water and running the engine at the same time but would not want to put a valve in there because if it was forgotten it would be tragic. I hate to have to shut down one AC pump to make water. This would be a 1 year solution as when I haul out I think I would install a seperate strainer in the future. Thoughts??

I don't think it would work at all. One pump's suction head will back flow the other and air eventually cause the system to not operate. You might could try a couple of check valves in the suction lines but I think in a raw water situation the check valves would eventually not seal.

I agree I thought about it after I posted it and said that would be a poor design. I don’t see tapping one of the AC pumps with a valve as they are just so hard to get to. I think the best way is a new strainer so this may be back burnered for now as I don’t see this getting done before my long trip to Bahamas

I don't have any pics of the process but here are a couple of the old hoses and you can see how the hose shows cracking on the bend that connects to the vacuum pump. I do have instructions from one of the SR members which was very helpful in confirming the process. The best advice I received was to pull the hoses out and reinstall through the heads vs the engine room. I drilled a hole though the hose and threaded the flat nylon line the marina uses for shrink wrapping boats. Worked great and is very strong stuff. No screws or bolts needed to connect a line to the hose.

Great job on that as I can appreciate the aches and pains the next day. I started that project last week and luckily didn't have to remove the lines from the head to the pump. R&R'd everything else along with duckbills. Seemed like everything in the engine room gets more deteriorated due to the heat I'm thinking.
 
@ttmott well the deal was so good I couldn't resist. Now it is game on to get this installed and working by July 8th when I leave for Bahamas. I ordered the breaker today and will pick up the wiring this weekend. Can you tell me more about your 3-way valve, size and where you got it. I am going to use the cockpit ac strainer like you did to switch for now.

Has anyone had the experience of having to replace a prop shaft? I hit something last week and immediatelly noticed vibration so pulled the boat and found a shaft to be .010 out of spec. Props were OK. Of course I asked if it can be straightened and the marina said it could be but would eventually lose the correction and go out of spec again. Does anyone have an opinion and cost of replacement?
Thanks.

Well, the marina is wrong. Bent shaft but prop is OK; how lucky can one get if they have to damage something! Heck look at my posts in the last month in the 500/52 Sedan Bridge threads.
A new shaft is upwards of $2K plus the wait time. Somewhere in your area are reputable prop shops; give them a call they can straighten without issues.

I had a shaft replaced and both props brought up to spec last year. Cost was $9,500 all in.

I can't imagine your prop is not out of spec if you hit something that hard to damage your shaft.
 
LOL... I am

@ttmott
Tom, what size is the hose out of your pump to the watermaker inlet?

Thank you sir, just building my supplies list for the project. Stopping by Boat Owners Warehouse tomorrow to do my shopping and pre-install work. Wifey is on here way now to Watermakers Inc to pick up my booster pump before she picks my up from the airport. Project is coming together nicely. Richard at Watermakers Inc in parts dept was great helping me get what I needed quickly. They seem like a great company and the plus is they are less than a mile from my boat.

Cool - it will be transformational in the enjoyment of your cruising. There is something almost spiritual to be said about hot long showers every morning.
Make sure you have a couple of TDS testers, a couple of sets of filter elements, and membrane cleaning compound on the boat.

Just got my inflatable fenders and air gun. Takes less than a minute to inflate each fender. Now I can deflate, roll up and store easily under a seat. These will work perfectly when we travel away from the home port and not take up valuable storage space.

Hi Grant,
I've been watching the Boats to Go site waiting for these to become available again and this week I saw they are taking pre-orders for June delivery. It would be nice to get back the storage my fenders are taking up but I wanted to see if you are happy with yours.

Thanks.
 
I have rebuilt both vacuflush systems one last year, worked perfect. This year rebuilt the aft system and I cannot get it to build enough vacuum to shut off. I have isolated it to the vacuflush by removing the hose from the toilet and caping the inlet and still not nearly enough vacuum. I haven taken it apart and checked everything and am at a loss.
Does anyone have any ideas?

thanks
JB
