25' Checkmate Convincor I/O to twin O/B's

Yep
Have used these for yrs.

Thats what holds the cushion on my sun lounge.
Was rotted when I bought it and had to rebuild it.

...1/4-20 threaded tee nuts, in stainless, is what you use to fasten cockpit interior side panels, along with the pvc board. you drill a hole in the preupholstered side panel for the tee-nut, in the strategic location thats best for your application, that has reach-around access, you hammer in a tee-nut into that drilled hole, and then thread into the backside of that tee-nut, a 1/4-20 STAINLESS stud, of the length you need to go through the boats side interior. 2 1/2 -3'' are most common. you can buy the tee-nuts at any good stainless fastener wholesale supply house, or online...

...and then, when you go to install these side panels, you don't/can't use locknut type nuts. you use a regular flat washer(or fender washer), a regular lock washer, and a regular 1/4"-20 nut. all stainless only. we always used a little 90 degree, 1/4" drive,(or 3/8" drive) air wrench with a deepwell socket...that you simply reach back there & zip down the nut with. goes fast that way & doesn't over tighten the nut.

I don’t believe Special K is a CM.

Gary, I’m glad you got the boat wet! Can’t wait for a ride someday.

Was the test ride at Delaware Res? Back in the early 80s, my dad and a buddy took a CM jetboat down there one cold December day for a test ride. They were the only truck at the main ramp. They put in and idled out towards the main channel. As they were running down the main channel on the east side, dad noticed the boat was filling up w- water (hose or something). They beached the boat on the far East side before it sank......and then had to hike thru briars and snow for miles to find a road and a ride.

**** like this is why this project ain’t done yet.

My brain starts more projects than I can finish!

Did this to my last Sonic too.

I don’t like the traditional anchor light that plugs into a socket the transom.
The socket fills w/water, corrodes and then doesn’t work.
The removable light gets lost, beat up, wet, and doesn’t work when needed.

The big one for me is the safety aspect.
On a boat that sits low at transom, high at bow, that light might might not even be visible to on coming traffic.

We spend a lot of nights at anchor and I want ALL traffic to see us.

Not quite as clean as not being there but I’m OK w/transferring from purely aesthetic to functional and safe.

Had to make a longer pole for this one then bend it to fit the form where it’s mounted.
Also had to fab the mount for windshield.

I really like how it came out.

Interesting lil tid bit is, where the lamp rests on the front deck, is a raised area that at some point in the deck molds life it used to have a socket there for the anchor light.

Ill glue down a small piece of rubber to cushion the lamp from the Lake Erie waves.

Instead of rubber, how about using the larger prong Velcro strips like we use to hold Sunpass transponder to the windshield. It is clear and the adhesive is strong but easily removed if needed. They sell it at HD and can be cut to size.

Great idea.
I shall use it.

Thank you sir.

Aw man, you noticed that

[tnelsmn]

...look into what they call "landau" foam. it was originally used on landau tops on cars. it is a closed cell foam, available in a couple different thickness's, the most commonly used is 1/4" on boat interior panels in the cockpit, etc. ...glue it to the panels, then wrap & staple(s.s. staples) the vinyl covers. use NO wood in the cockpit. use pvc board. all different thicknesses available just like plyrot. the thicker the more costly, just like plyrot. its what most boat builders have been using for 20+ plus years now. can be glued, screwed & takes a staple perfectly. no rot. does'nt loose its shape over time. can be recovered by the next guy. should always be used as covered material though due to UV. its available in a few different colors, the most common being white. its available in a few different surface grades. the ruffer the surface grade, the cheaper the price. any color you can use, as its getting covered. also people think that just because its in a boat, that an interior can be hosed down all the time. false. an interior job should be treated the same as the interior in your car. covered, dryed, treated, etc.

Yep.

One of my favorite tools.

Drastically reduces tuning time on a new/unknown set up.
Especially idle and mid’s.
Will get you close on mains.

Load the jets/tools in the back of the truck and leave the boat strapped on the trailer.
Hit the ramp mid wk, mid day (no one around), back it in far enough to get the exhaust under water to put back pressure to the motor to set idle, do a pull, pull it to top of ramp, make changes, repeat.

Pull plugs to look at pistons etc.

In the Fla heat, I even set up anchor shades in the cockpit, over the motor to give shade.

...yes. have been meaning to mention depot. was there a few days back & saw they stocked two or three different thicknesses in white. 1/2''...which is the most common for cockpit bolsters & seats, was $72.00 per sheet, which was a 4 x 8 full sheet. been meaning to post that... to add about the 1/4'' landau foam, what i neglected to mention, is that it is used to go over the top off your roughed in regular seat foam, to make the design super smooth, to accept your already sewn-up vinyl cover that you pull over & staple on the bottom. another trick that all upholsters use, is throwing a big piece of the thinest visqueen you can buy, think it was 1 milimeter, over the seat or bolster, before you try & slide the vinyl cover over the top. it will go on MUCH easier.
