Matt_E Roundnose Rebuild Thread - Motor Update for 2009

[Matt_E]

I am guessing that a few of my pump or rideplate inserts may be leaking.
I sealed them, but perhaps when I put bolts through them, the seal broke.
I find it unlikely though, especially with the amount of water I got.

When I had everything empty in there this winter, I noticed that I had a break in my intake tract, right by the pump shoe.
I glassed it from the inside, but not from the outside.
Perhaps the pump pressure blasted off the glass work.

crazy how much pressure is forced into the hull from riding. someday i will make a watertight hull. it sure is nice to be able to drain the water out until then.

 

[Matt_E]

Yup!
I am extremely pleased to have those drainplugs. I'll leave em out unless I am riding.
By the way, what drainplugs did you use?

 

[D-Roc]

i used little brass plugs and steve used 1" abs plugs with rubber washers/seals. i will probably switch to those ones because they sit pretty much flush, where mine stick out a bit.

 

[Matt_E]

I used actual boat drainplugs, also with rubber seals.

Notice the sweet Rearview mirror style Yamaha logo. Think "Ambulance"
That's what those couch mirrors are for.

I thought I was just looking at it from the wrong side !

Great job Matt !!!

 

[DAG]

Rear view mirror script.

that must mean your slow

It's done!!!
The nosepiece wasn't fully attached, so I took it off half-way through the ride.

made this mistake, and have been w/o a nose nearly all season :17:

PS: love the paint

 

[Matt_E]

Bilge shots, as requested.
I warned you.

 

[Mouthfulloflake]

is that a kawi throttle cable?

 

[Matt_E]

Yessir.

 

[Mouthfulloflake]

from a stand up or sitdown?

I think ive got a 750ss cable... I wonder if it would fit.

 

[Matt_E]

From a 93 750SX

 

[750SX]

What is the reason for using the kawi throttle cable?

 

[Matt_E]

1. It's a much better cable than the Yamaha counterpart. (Thicker, better built)
2. It costs $28 brand-new.

 

[750SX]

Cool. I thought maybe it's shorter. With the SN cable in my RN I have enough throttle cable for a plus 10 pole lol. Mine is -3 so I'm going to have some extra. The ski looks tits Matt.

 

[Matt_E]

Thanks for the kind words.

I am sitting at -6.5 over stock, so there is plenty of room.

Hey Matt, bummer it's already leaking, but I'm sure that just makes you happier that you used the poly foam :bananajump:


I was asking you about the pump inserts the other day, when I decided what I was going to do. Instead of using a solid type glue, like the bostik you mentioned, I threaded the bolt up into the inserts so the end of the threads was flush with the insert, and the totally coated the top of the inserts with about a 1/8-1/4" of 5200. The bolts backed right out when the 5200 was dry, and I don't have to worry about those pesky things leaking! I mainly used the 5200 because I already had some laying around though

 

[Matt_E]

The bostik adhesive I used is very similar to 5200 - def. not solid type.

 

[Kennay]

Ah ok. I have very limited experience with other stuff aside from 5200. I just figured it was something similar to the blue yamaha glue or construction adhesive

I'm actuallt taking a lunch break now... stuffing that ski with the poly foam is as simple as it looks. Hopefully I can pour a layer of foam on it today!

Edit: ISN'T as simple as it looks

 

[Matt_E]

How big of a sheet did you get?
