Motors arrive


and get mounted.

Awlgrip and bottom paint next...

This week was priming all of the exposed areas where I removed the original paint around corroded areas. Also the aluminum deck was glued to the hull, screws set and then covered over...

Original Deck:

Deck glued down.

Hey looking great. Nice job. You are an inspiration!

Looks real good. What is the shaft length of the Evinrude engines? Did you extend the transom?

The details of the transom can be seen clearly in the several images above. The insert into the original notched transom that provides five-inches of higher splash well height does not appear to be attached to the original hull. It looks like it is held in place by the aluminum riser brackets holding the engine, and its thickness to much too small to be a structural support for engines of 500-lbs or more.

New tank arrives...

The engines look like they're thru-bolted into 1/2" thick x 2 x 4 aluminum L-brackets, the bottom bolts going thru the original transom. I think the arrangement is strong enough as long as there are large enough backing plates on the inside of the transom. It roughly resembles a low setback jackplate in principle.

Acseatsri,

It's a manufactured bracket good to 300hp.

Rotten plywood removed from the tank deck cover...

Hi All,

After much delay the tank cover is finally repaired/improved. After days of cutting, sanding and grinding I turned over the thin fiberglass top to the boatyard to finish.

They used three sections of a glass/balsa sandwiched laminate and glassed it to the thin original decking.

My impressions are that it looks perfect, is much lighter, and much stiffer than the original. (I have not seen the bill yet)...

Hats off to the SF Boatworks for quality workmanship. Next step is to cover my new tank.

I am enjoying the many comments and photographs of this renovation, and I am sure many other readers are, too. Keep the posts and pictures coming. I am looking forward to seeing the end results and the boat on the water.

Thanks Jim,

Here are some other miscellaneous repairs:

For some reason CPD liked exposing foam on this rigging job. Maybe a deadline for shipping her to Alaska.

In any case two big holes for the fuel lines (using bent copper tubing), they ran in and then back out of the bait well. In addition, lots of holes for the tow bar mounting brackets (I did not get the actual bar).







They also used white PVC pipe to line the big wire tunnel into the cabin (jagged sawzall cut, silicone calked). For that we installed a pre-made fiberglass tube and glassed it in (i'll add the pictures of that repair later)

After forever She is launched!!!



Initial "day-one" test: [4 blade Cyclone, 19 pitch]

70 Gallons on-board
Max Speed 54 WOT @5500
Happy Speed for SF Bay = 26mph @3050 RPM
Non-planing cruise 10mpg @ 1600

I have not done exhaustive testing (upwind/downwind, trim settings, etc) just a ferry ride from SF to Alameda. I did hunt down some choppy seas (between Treasure Is and Point Blunt) to find the most comfortable RPM.

These E-TEC engine just don't stop; set the RPM and they just plow along--I just love it.

Beautiful boat, wonderful work, congratulations. Don

AMAZING. Great job.

Pete--very nice work and very nice of you to follow up with new pictures.

Re the E-TEC engines: my E-TEC runs like a diesel. You set the engine speed, and that is the engine speed. Steady engine RPM no matter what. I love that aspect, particularly when you have to run into some head seas. The engine speed is not hunting up and down.

Enjoy your new boat.

Thanks Jim...

I did have a question, can I retrofit my 2011 e-tecs with electronic shift/throttle?

Pete
