MOJO '78 Mako 25 Rebuild - Got my Mojo workin

That’s a lot of hard work right there. Looks great.

Were you going to glass anything into the bilge to screw pumps and other misc things into?

Hey man this thing is looking awesome, that fortune cookie said it all…nice work!

filleting

building a beam to reinforce the aft edge of the fwd fish box hatch

Then adding 2708 layers and foam core to further reinforce the same area

trimmed and puttied

glassing the same bulkhead areas that were filleted above; the cut out strips laid on top the deck are set up on the corners in a manner where I can pull each one and know where it goes below deck (each corner below where they’re laid in the pic)

Forgot to get pics of finished glass. Results weren’t bad considering barely being able to reach in there on the below deck side!

clamping and glassing resized hatch

Hope you are wearing your PPE, thats a lot of glassing! If not, you won’t have any brain cells left after the project :slight_smile:
Looking good!

Yes. I have some parts I am going to glass to the bottom of the hull and also to the top of the stringers. Waiting until I put more glass in the bilge and then some surfacing veil. While the veil layers are kicking I’ll put in the thru-hull mounting block, bilge pumps mounts, wiring conduit mounts, fuel filter mount, sea chest mounts and macerator junction box (small sump/reverse sea chest). After all that comes the skim/flood coat, which hopefully won’t be much since the surfacing veil 1/4oz glass layers really smooth things out. It won’t be perfectly straight like it popped out of a mold, but what I’m wanting is for the bilge to be smooth and easy to keep clean.

Trying to decide on whether to build in a “drawer” or shelf system that will essentially be right under the transom live well to increase storage use of bilge. Weights, spare prop, etc. can stay there. The only things back near the transom will be bilge pumps and high speed thru hull pick up. Everything else will be up near the cockpit bilge hatch within easy reach.

“Macerator”? Are you placing a head in the console?

waste pump out goes like this

fwd fish box port plug - stbd plug to 1 1/8" hose - 1 1/8" hose to port fish box fitting w/ plug - stbd fish box fitting w/ plug open to port fish box - stbd fish box drain to 1 1/2" fitting & hose - 1 1/2" fitting & hose to port valve at junction box - stbd valve at junction box which has bypass valve lowest point of system to open junction box to bilge (bypass valve open when boat stored) when in use, then line from junction box to whale gulper pump discharges thru 1 1/2" hose and thru hull outlet

The purpose of the setup is so that I have the option of flooding either rear box with ice water from the fwd box, draining thru either cockpit fish box, and draining either or both at once to single pump or to bilge. I did not want any plumbing going under the fuel cell, and I want the bilge to be isolated so the boat cannot carry much water if there’s a leak. Most of the back end of the boat is going to get partitioned with solid glass and have areas filled with foam. This is necessary IMO because the back of the boat is going to normally have a lot of weight in it (fish, people, live well, 4 stroke motor). Any extra water carried in the bilge will be a big problem quick. Btw, the whale gulper can also be a third bilge pump by opening the bypass valve and shutting the two fish box valves (all accessed from cockpit bilge hatch). The waste pump then will pump water out the bilge far faster than a bilge pump can. Another practical benefit from the bypass valve is that if the waste pump goes out, then I can empty fish box waste with the bilge pumps or the garboard drain if on the trailer…

Trying to make a really seaworthy and easy to use boat.

A well thought out plan for sure. Moving right along.

Phin, you are a man who knows boats for sure :sunglasses: Too bad most manufacturers don’t think like that.

Very nice workmanship also.

At this rate you’ll be slamming Grouper on that boat before the season ends!

I’m sure you thought about it, but do you think a seachest would be appropriate for your boat?

Pumps last longer
No air locks
One thru hull

This boat will have four needs for raw water.
Transom well
Fwd well
Raw wash
Aux outlet- backup for any of the above or portable aux livewell (removable well that can ride on transom or deck)

She’s really starting to take shape now.
Nice work!!
Thanks for taking us along.

adding glass for new fwd box floor

making flood coat putty and structural putty-

Inside the white bucket on the left you can see milled fiber sitting on top of cabosil. Inside the bucket on the right is Q cells (microspheres). One paint can has the dense structural putty I make with resin, cabosil and milled fibers, and the other paint can has the lightweight finishing putty made with resin, cabosil and q cells.

puttying (structural)

foamed

glassing

sanding

about to bond deck to stringers

more putty needed around top edges

budd

its looking great, I applaud you for the time spent, she will be well worth it.

Thanks. Lots more update pics soon!

glassing in a reinforced area for high speed thru hull

puttied

flood coating the bilge

fwd fish box floor extension and transition getting more glass

glassing

Jason cutting down the glass, which will let us get a better horizontal-to-vertical radius, in the section of the stringer that I had to cut down to match the other stringer’s height

sanding the cut and the old fir core to round it over for a good radius for new glass

puttied

heavy triax laid over

tabbing in the fwd bulkhead- I guess I forgot a pic of the finished fillet putty before glass, but Jason got a pic of me puttying the aft side

Just got off work…storms bigtime here in Augusta all day…flooding some areas.

Anyway, you have some real pro workmanship going on there. Looking awesome man! Cool pics.

Good for you!

Cant beleve you have time to work takeing all the pictures! Awsome
posting,wish I had that much energy! Cant wait to see finished project!Thanks for the updates.

This. Oat is going to be f’ing awesome. Your work on this boat and the level of documentation is absolutely inspiring. It’s official, I am jealous!
