Blazer Marine Slingshot Build!

[Mario Johnston]

Sweet redemption!
Little more sanding to do til perfect!

 

[Mario Johnston]

Now this is more like it!

Onto the next thing: setting stuffing tube and sorting out throttle servo placement.

Things moved pretty quick today, drilled and tapped boom tube hardware in an hour or two. Washers come later on!

Machining parts at my buddy's shop tonight.

Also cut rudder down to appropriate length.

Small step before work today, lining up upper and lower cowls

Things are moving along quickly nowadays.
Finishing one step almost every day. Last night I set the boat up at an angle and poured the epoxy for the stuffing tube support.


Finished, set and cured.

Put some reinforcement fiberglass to hold the carb shield on. Just cut a couple of strips 3/4 X whatever to lay on the inside of the shield. Or you can order one now for replacement.

 

[Mario Johnston]

Definitely, Bob! Its currently just tacked on with CA to ensure the right fit. Will reinforce this week

what turn fin are you using for this hull?

what turn fin are you using for this hull?

I'm not certain as yet. Spoken with Brian Blazer about one briefly but I still have a ways to go before i'll need one I think. Will be looking into one seriously next year

I tried a few different Fins and the Blazer fin works the best on all the slingshots I've built.

Mario, in the picture where your hand is holding two rudder blades, on the tapered front edge of he rudder, you see a wall on up on the front of the rudder. Would like to ask, does anyone taper that area !! That area will seat below the transom ? If you look at the picture that shows the strut (knife edge in the front of the strut) and bracket assembly and the rudder bracket assembly mounted on the transom, you can see the area I'm taking about, that area will seat below the hull bottom. Your build is looking good, Good Luck.

^^^ I see what you're saying, john.
I suppose it wouldn't hurt to remove some of that upper forward wall.
For the most part it will be obscured behind the rear sponson when the boat is on plane but i may look into cleaning up one of my rudders in this way. Good eye!

 

[user 21992]

Thanks Mario, I've been using my belt sander and carefully tapering from the L-Shape corner area of the rudder forward and this can be arched (like a reverse tear drop) so as not take to much meat from the rudder and still take away that wall. Great Pics !!

Had a rough day at the lake today with some nitro engine gremlins ruining the day. SO, I decided to work on this again to take my mind off things.
Wasn't entirely happy with the cowl fit, so I began sanding/straightening edges and refitting lower carb cover. Much happier now!

 

[Mario Johnston]

Exciting day today!!
Header & manifold arrived in the mail, couldn't wait to throw these on so I could begin fitting the cowl!

 

[Mario Johnston]

Made a neat little cut-out for my plug and lead today. Just about time to prep cowl for paint.

 

[Mario Johnston]

This is a great feeling!
Still a long way to go, goal is still to have it overboard by spring 2021

8 month update:
Wanted to see if it'd be possible to keep the cowl seated on top of the tub but there's too much of a gap towards the rear. Started trimming to sit down inside the tub instead tonight
