Meet my new engine! A Beta Marine 20hp 3-cylinder. I've been wrestling with the decision to repower for over a year now, and looking at several replacement options including the newer Yanmars, Volvo, and Beta Marine. No one reason forced me into this decision, my old engine still starts and runs. But after examining the situation I felt the case for a repower was strong enough: - The old engine is 35 years old and raw-water cooled. It has parts with structural rust, a broken engine mount, cracked exhaust manifold, temperamental throttle/transmission linkage, poorly performing alternator, and a number of other mild-to-moderate issues.
- Major parts are no longer made for it - I bought a spare engine and have already been cannibalizing it for things like a new raw water pump.
- It has occasionally overheated during normal operation even with good impeller flow, leading me to believe it has hot spots or blockages in the internal cooling channels.
- The zincs have not been changed in likely several decades and are frozen - removing them would probably take a pneumatic impact wrench.
- The new engine is way lighter, 100 lbs or so.
- I am wary of pushing the engine hard or for long periods of time for this reason - I don't consider it a reasonably reliable backup.
- The cost of maintenance over the next 5 years (with possibly a rebuild) at this point is a significant portion of the replacement cost with a nonzero probability of unsatisfying results anyway.
So I'm biting the bullet and repowering. I've chosen the Beta for its small size, design for easy maintenance, and overall positive reputation among sailors I've found in my research. H&M Marine out of Sausalito will be doing the repower. I'm opting for a 20hp as by my calculations (and experience) my current 15hp is on the low end of what my boat could use in terms of power. My 2-blade feathering Max prop will be adjusted in pitch to accommodate the increase in horsepower. With this change it occurs to me that I've replaced or upgraded almost every major system aboard the boat! But I also know that Ananda is going to fulfill her mission and be everything I want her to be for me for for the next 10 years.

This is our last weekend of work before my dad heads back to the cold... I mean, back home. We've spent the last few days fairing, sanding, and scrubbing down the deck, and tomorrow we're hoping to tape and begin the Kiwigrip operation. So far things have been going well though! The new nav station is really coming together: All switches are wired now to the fuse panel now, with only a few loads remaining to be hooked up (autopilot and radar I believe). The electrical cabinet is looking quite full: I've made a second electrical cabinet in the cupboard behind the head, which holds both the controller for the head itself as well as connections for the navigation lighting, both running lights at the bow and all lights on the mast. On deck work continues as well. Here's the new Scanstrut radar pole partially installed: Also, I finally installed the bowsprit today: It looks awesome. I can't wait to rig up the bobstay and actually fly my asym from it.

Kiwigripping has begun! Here's the lovely Crystal helping me tape off the deck fixtures (on Valentine's day no less, how awesome is that! I'll be taking her out to a lovely dinner tonight of course: Test patch applied: My dad working on the bow while Crystal supervises to make sure he doesn't drip anywhere: I also got a picture inside my forward electrical cabinet for you guys. Ignore the one wire that's connected backwards - I was debugging whether the anchor light at the masthead was installed backwards. It's not lighting either way, so it looks like a trip to the top of the stick is in order for me:

Today was my dad's last full day in town. We accomplished three major tasks: - Last night the Espar heater refused to start, at a time when it was much needed thanks to a cold front rolling in with some fog. Investigation this morning revealed that the fuel line had slipped out of the fuel pump intake compression fitting! Turns out it was flared improperly. We corrected that and got the pump primed again.
- We installed the traveler track! Complete with the board in the old trough. It looks so badass. I can't wait to rig it!
- Finally, we finished painting the whole deck with KiwiGrip! The transformation is incredible, I barely recognize the boat. I know it won't stay this clean for long, but just wow.
So here's some pictures of the finished product! We're still debating what to do with the stripes - I thought they would look good au natural but now I'm leaning towards painting them with a smooth white, perhaps with some gloss. (I liked the idea of linking to the pictures so I did the same for the new ones) We went out for margaritas to celebrate. When I got home, I had four packages at my door - a SeatalkHS switch to connect the radar to my chartplotter in a more reasonable way, more FRP for backing plates, etc, bolts, and more hatch sealing strips (that won't be used on my windows, but will in fact come in handy for other purposes). Work is never done!
