Day 139, 4/21, Autopilot drive connection, Deck priming, sanding between layers, 8 hours

-

Autopilot 

Finally, connected wires from autopilot drive to Raspberry.  looks it works well and able to turn rudder easy and fast. I did not installed end switches and rudder angle sensor, so no wild play now

 

Self turning wheel video - Dry test video. Rudder controlled from computer. On Video motor power set to 10% max. Can't wait to install safety switches to try to do full speed run test.

 Deck 

Still working on deck painting prep work.
This day did sand between layers. This time wet sanding.

I do not know what went wrong, but PrimeKote  did not self-leveled and as result i have pretty deep brush marks everywhere. and now i need to sand a lot to clean the mess.

Second mistake, i wait for a 2 weeks before sanding and primer have got very hard to sand.

Couple areas, where I forgot to tip primer and just roller texturing left was way easier to sand, so, likely no tipping any more on primer.

After 10 hours of sanding I think i am pretty close to be ready to put second layer of primer.
I washed out off  all grindings and after drying found ~10 places where I need to do some small touch-ups  with putty. Likely will do after work evening or lunch time during the week.

Day 183 1/5/25 Take engine home.

Engine Take engine from the boat and move to home garage. Easy to say, hard to do. Water level in the lake now is 40ft below normal level. And total height drop between parking lot and docks about 70-80ft.  Marina has no lift, ramp or crane to move something more than 200 lb up way. Only way is very long stairs with 140 steps.   View form the parking lot...    Staircase we climbed up. Yes, you can see the lift, but it is only 200lb capacity and no way to use. Picture was made on the middle of the process. Based on engine spec it has to weight 400 lb. It is a lot but should be more or less bearable weight for 3-4 people. Challenge was accepted, but looks like it is heavy enough to do a problem ;-) Moving from boat to dock was very easy, just hook chain hoist to boom lift it  and swing boom to the dock. put on a dolly and roll it to staircase. After an hour of planning we (My son and I) decided to use blocks and ropes to slide it up. We mounted engine on the plywo...

Day 138, 4/6, Deck priming, 2 days, 8 hours total

 Deck Spent a day to wipe all to clean, then de-greaser, then solvent, and then priming.  Surface area is not too big, but still be ~400 sq.ft.    I did wiping and cabin top at one day, cockpit and area next to toe rails in second one. Primed only area plan to paint glossy. non-skid paint does not require priming, just washing with detergent, but it will be later.  Observed two problems  first - rolling and tipping leaving brush marks  even when 25% solvent added. Second - (actually helps to maintain first) I need second layer because  one layer of primekote does not covering well. So, I plan one more gallon of primer and one mode day to of sanding and one more day of priming.   End of day1     End of day 2
