I was thinking I could talk my kids into packing a towel into the shaft log on the outside to slow water JIC the worst happened.

I signaled retreat and scheduled a haul today after messing with the port seal and two sea trials. Tempted to do both seals (again) while we're out. Also, contemplating biting the bullet and having the bottom soda blasted and getting new bottom paint. I did not have that in my budget this year.

My own soda blasting starts Monday. 450DA

Highly necessary in my case due to previous owners not taking care of it correctly.

Also handling 3 small osmotic blisters, ranging from a quarter to a lemon in size.

Although Sea Ray engineers named the 1990's 450 "THE ICEBREAKER HULL" all that underwater real estate needs to be properly protected.

Properly applied, that epoxy barrier coat will protect the biggest non-replaceable part of the boat.

Not going to put mine off.

Soda Blasting Her Bottom

Made the decision to soda blast the bottom. Have 3 small blisters to repair as well - will use West System & Collodial Silica and fiberglass cloth (if needed) - no stranded mat and no micro-balloons. Closer inspection showed numerous chips and adhesion problems on the bottom paint. Lots of...

So, found these. I pulled the trigger. https://www.tobatechnology.com/product-page/marine-digital-gauges

They work with all traditional resitance type senders and have a lot of capability to do alarming and other nice features.

Interestingly, emailed FP today to ask about guage/instrument panels, and they don't have ours. So, I am going to send my originals and they are going to template them so everyone else will be able to get new ones if needed.

Does this unit display multiple temp sensors? I always wonder if I should have more than the one temp gauge at helm. Such as exhaust temp, turbo temp, v-drive oil temp.

Incidentally, spotted a 450 EB at Fisherman's Warf Marina, Venice, Fl as I cruised on by. Had a faded blue bridge Bimini. Pretty sure it had a brokers sign hanging from the bow rail.
 
Hey all! If anyone is interested, we started a YouTube channel of our trip down the ICW from Bear Delaware to Palm Coast FL. We have a 2002 450 that used to be named Searenity and we changed it… to.. Peckerhead
Trying to post weekly videos. It gets interesting. Especially when our rebuilt transmission went bad again. I’ll be posting that video next week.

It does. It can handle a tach, voltmeter and 8 other resistive senders.

Hi @RetiredSubGuy here is the link, but looks like the pics are not linked correctly anymore.

Still waiting on the guage units, but here are the new dash inserts and a comparison. Space for some thing outboard. Also, had the alarm deleted (mine had been clipped by the previous owner) and the MEMUs do alarming. I'll need come up with something for the bilges.

I'm interested in this Toba unit. Does this replace the Sea Ray systems monitor. All I ever see is "All Systems Normal" unless my foward bilge pump activates occasionally, in the grey water overflow sump. Toba isn't NMEA, is the Sea Ray monitor? Would be nice to see more detail of every signal going to the monitor.

It does do alarming. My Sea Ray monitor was clipped by someone in the pastb, so it has never really been helpful to me. I watch the bilge pump lights and I have warning horns for temp and oil.

Toba allows to set an alarm on all guages and it sounds a horn and turns the guage red for the alarming guage.

I am probably going to take my existing horn system and wire it to bilge pumps, leave the temp and press warnings attached because it doesn't cost anything, but the Toba will become the primary alarming system for engine/transmission issues.
 
I had another issue with my fresh water system. The Jabsco accumulator tank developed a crack on the bottom. Turns out Jabsco discontinued the model I had (12573-3000) and replaced it with a new model (30573-0000). The old tank had a single outlet/inlet and was run off of a T fitting near my water heater.

The new model was designed to be mounted in the flow of the line, with two ports.

So I tried to make my job easier. I had the not so brilliant idea to mount it in the same spot, using the same single line and capping the second port with a 1/2” sprinkler cap. No such luck, the cap leaked.

I ended up removing the T fitting altogether and then mounted the tank a foot or so aft of the water heater, in the cold supply line between the main water tank and the heater, following the Jabsco directions. Sometimes there are no shortcuts.;)

I still don't even have one, like many other pieces of my boat the previous owners mechanic just decided to leave it out. I haven't had any issues without one in the system. I may just put one in one of these days, but I remember somebody just used one from Lowes after going through several Jabscos. My friends Hatteras has just has one from Lowes.
 
I have an accumulator at my potable pumps. Wondering if another exists at the water heater(?).
 
Get the 1 gal metal one from Lowes. It's in the hot water heater parts section. I bought a whale one (I think), it was over $100. The Lowes one was I think $40. Same part. Once you have one, you'll never go back. The small black ones stink and are too small for our boats. One of the pluses is that if you turn off the pump(s), then come back in a week or so and you turn on the pumps and they do NOT kick on, you know you do not have a leak anywhere.
 
Do any of you have a galvanic isolator on your boat? If so, where is it located? I'm going to install one soon, and would like to get some ideas on a good location that is close to the power cord inlet, but doesn't get in the way of accessing other things. Offhand, it looks like on the base of the box supporting the generator would be best. Thanks!

I have a Charles C-Power Isoboost 50, isolation transformer. It is mounted right in front of the generator on a stand to enable crawling under it to access the seacocks and bilge pumps beneath the genset. It's pretty big. Have to lay on top of it backwards to get my legs down into port, aft corner.
 
With boating season around the corner I checked out the market again to see if there were any new listings. How about "D'Anna" from Maryland! The cockpit cover is really nice on this boat and she appears to be very well cared for. Found the HIN and added it to the list on the first page. 110 boats on the unofficial registry now. Listed at $225,000
