View Full Version : 2006 X1 Engine Cover - Walk-through

10-03-2013, 02:04 PM
Well after ripping the rear engine cover vinly for the 2nd time. I decided a different route was needed.

I stripped off the foam and vinly and was left with a 5/8" aluminum and honeycomb deck. Took it over to a aluminum fabrication shop and we came up with a design that should be pretty cool.

Hes going to cut out the same size plate (basically a rectangle with 2 little cut outs to reach the handles better) out of 1/4" aluminum plate. We are then going to attach (2) 2" blocks where the hinges screw into, and 2" square pipe will reinforce the edges and sit on the brackets of the boat. Im going to have seadeck.com send me a template kit and make a template for the top part and have it match the colors of the boat and have the mastercraft logo placed in it.

This should
1) clear the airfilter / valve covers which currently where being squished by the oem sundeck as the plastic bin is cracked etc...
2) Allow a nice walk way to get to the back of the boat instead of stepping on the vinyl

I will post pictures are we progress. Hes doing everything in autocad and a cnc machine, so once we have a good prototype it should be hard to duplicate if anyone is interested

OEM piece ripped apart for now.

Post up some pics when you get it done. I have been thinking about adding a walkway to mine over the winter.

10-03-2013, 02:21 PM
GREAT idea-been thinking about that for mine, engine cover needs a re-do.

10-03-2013, 02:59 PM
Will do!

Pretty excited been wanting to do this a long time!

Some ideas I could use some help with. Aluminum on aluminim is going to rattle (engine cover sitting on those rails... Will need some kind of rubber strip to put under it. Also im wondering how much louder the engine is going to sound resonating off the alum. I was wondering if some kind of sound deadening material could be used. The type used in car ( dynamta etc..) but not sure how it will work with heat...

10-03-2013, 03:04 PM
Wrap the rails in black carpet. PO did that on mine and thought it was factory. Makes stepping on rail easy and no corrosion or scratches to the metal to show (or rattles as you mentioned). Surprised M/C didn't do this from the beginning

10-03-2013, 03:05 PM
good call!

I can take the rails out while this is being fabricated and get that done. You think they just glued the carpet?

10-03-2013, 03:29 PM
Yup just glued on. Looks great and really finishes off the engine bay. Used a simple black carpet- not too thick or very expensive. Looks like cut it out, turned over and sprayed carpet contact glue on the back and rail, and wrapped it up. I'll post a few pics when i get back from Nigeria.

10-03-2013, 03:56 PM
Nice. I think im going to cover the bottom of the plate with this:

Dynamat HoodLiner - suppose to reduce heat and noise
SeaDeck the top
Carpet the rails...

10-18-2013, 02:49 PM
How is this project coming along?
Any new pictures.....

10-30-2013, 12:36 PM
Hey, I got the template made a while ago... and finally got the walk through made...

I guess the shop forgot our discussion about the valve covers and put a cross beam right in the middle, but its not welded to anythign where i need to cut it. Gonna have them chop it off and then tack weld the ends to the plate.

Contacted SeaDek and sent them the .dxf file...

Looks Good! Can't wait for the finished job!

10-31-2013, 12:28 AM
Looks good...So is the seadeck going right on the aluminum??..no foam.

10-31-2013, 11:53 AM
Seadek is foam... 6mm closed cell foam. I sent them the template and they are going to cut it out in the grey over black teak look with the mastercraft logo in the middle. The teak "strips" will run bow to stern and the logo port to starboard

10-31-2013, 01:49 PM
Ah....thats gonna Looks sharp.

10-31-2013, 02:24 PM
SeaDek order is placed...

I went a head a reinforced the rails that the plate will rest on and then painted them. Im thinking I will just pick up the seadek step kit and stick the 4 pads on the black rails to prevent vibration noises.

The bottom the engine cover will be lined with Dynamat hoodliner, should help reduce engine noise and heat.

Fresh coat of rustolium hi temp heat / rust protector:

Got it installed last night, and went for a cruise. It actually sounds quieter for some reason at idle. At wakeboarding speed the sound resonates different, not louder or quieter just different. The hood liner and hindges come today so that should help keep the noise down. Sea dek is working on the pad.

It is damn sturdy though!

11-01-2013, 01:00 PM
Looking forward to seeing it with the seadek.

Do you think the reinforcement on rails was actually necessary then? The stock weight gas shocks will be strong enough still?

11-04-2013, 11:43 AM
The rails that it sits on did not line up with the 2" support beams welding to the frame... with the handle cut outs and without getting even fancier i was easier to just weld the 1" square tubing. before it was sturdy, but i could see 1 area where it did not sit completely on the rail. Now with the extra support it is solid!

I installed the dynamat hoodliner on it this weekend.


The deck never got "hot" but it would get warm (similar to the ski pylon) now with the hoodliner, it doesn't even get warm. It is pretty quiet too.

What no lights after that beautiful job ;) - -- just sayin... :) Looks awesome...

hmm had a thought... with it being that strong you could put a high pressure actuator to take care of those folks who think our boats run on "thanks" - and in the fall you could have one cool pumpkin' chucker. :D

11-04-2013, 11:53 AM
haha, that would be awesome!

I basically was that when i tried to attacht 2 100# 20" shocks to it... i couldnt close it!

Hoping the 2 45lbs 15" shock struts will do better

I have strips of LEDs i could wire up... maybe ill do a ring around the inner part so it glows... DING! idea!

11-04-2013, 02:40 PM
Looks great! When the vinyl fails on our 02 Xstar we're going the same route. For those of us with MCOCD... Thinking about any type of finish covering on the bottom of the panel? Paint, Rhino, LINEX, Carpet??? Leave the dynamat as is and cover the frame and rails with carpet?
How far ya figure you could chunk a punkin with 2 100# shocks??:rolleyes::D

11-04-2013, 03:33 PM
I painted the exposed sides with high temp black paint (similar to the rails). Im guessing you could get the whole thing power coated as well.

11-04-2013, 04:19 PM
Looks really well engineered

11-05-2013, 01:59 PM
shock struts are in and working....

2 15" 45lbs sturts.... had to upgrade from the 15" 30lbs ones the original engine cover had.

Got the rendering from SeaDek, and need some suggestions on the writing direction.

Should the "Mastercraft" writing be legible when you are standing on the swim deck facing the front of the boat?

Or should it be legible when you are in the boat facing the back.

Basically should the righting go port to starboard or starboard to port....

11-13-2013, 10:14 AM

I think it needs to go that direction.

11-13-2013, 10:42 AM
Port to starboard when looking from behind the boat forward. Definitely.

11-13-2013, 11:02 AM
yup changes submitted...

11-13-2013, 11:19 AM
^^I see where MC got their 2014 surf tabs from^^

11-13-2013, 12:13 PM
I know that it is not quite the same application, but here is a shot of my SeaDek pad on my Tristar...Port to Starboard...

11-13-2013, 12:33 PM
Yea i think when i told them port to starboard they just didnt realize which direction the drawing was facing...

12-06-2013, 03:14 PM
Well it finally showedup... will be installing it soon...


12-06-2013, 03:27 PM
This is gonna look fantastic!!!

12-06-2013, 03:53 PM
How much to have that fabbed up?
Love it-

12-06-2013, 03:56 PM
I am on the record as saying a couple years back that if someone could do this - you ship them your hatch and they send this back, they'd never want for business. And if you could do something small on the seat to step down on - double wow. Looks great. I want this.

12-06-2013, 04:11 PM
I have the auto cad file for the top plate, and the template for the foam for seadek. If anyone is interested let me know.

Ill post pics of it installed tonight.

about $250 for the seadek, and $500 for the platform and frame... im sure someone with access to a cnc or laser could have it done much cheaper.

12-09-2013, 02:19 PM
Here it is installed

That turned out great! I have been following this thread, and it looks very cool for sure

12-12-2013, 09:28 PM

12-13-2013, 09:27 AM
That looks great, I only wish I had seen this before I had my interior redone last spring...

12-13-2013, 10:25 AM
Man, that is classy and sexy!

12-15-2013, 03:06 PM
