Default Complete Mako Restoration UPDATE PAINTED Tower installed

Hey guys. I've started a new project. My floor finally gave out with my tower and we decided to pull the cc, leaning post, tower and tank to see what we were dealing with.

Plan of action
Remove deck and water logged foam
Customize the front deck (to look similar to dorado or Shaffer)
Repainted haul sides
Sand and paint gunnels
Add a pitch well in the bow casting platform
Add in deck storage
Fish boxes
Add support to cap

A little background on this boat this s the 2nd overhaul in 5 years, the first I feel I was taken advantage of but that's water under the bridge and I'm ready to have this done right!!

This is where I'm needing some advice. The shop doing the work feels I should leave my original stingers in do to no rot and how good and strong they are. They want to build up the excisting stringers with composite material and wrap them with matt and then with a quadro woven material (not sure the name of it). Then lay my composite floor on that.

I will be updating this thread as we make progress. Hope you all enjoy!

What do you all think, would you leave your original stringers in if they are in good shape?

Here are some pictures of the original project and of how the boat sits now with some of the deck removed.

If the grid is in that good a shape and he's basically going to encapsulate it, the only negative will be a few extra pounds of material, especially if he uses a light composite because your original grid will still carry most of the load as its in tact.

Was the transom so bad he had to cut it all out? outside and inside?

If there's no rot or delaminated areas you should be fine.

Really don't know. It felt pretty solid but we wanted to close it in. Since then I have learned cutting it out completely is not always the preferred method. The old shop that did the original work is an old forum member here but he went out of business.

Many manufacturers used little glass on the stringers and relyed on the wood itself for strength. On a rebuild I believe it is an option to glass over existing stringers so that the new layers of glass become the primary structural member. Adding a composite to the existing stringers will cut down on the lamination layers.

There are many ways to do stringers and it is often the owners decision of what suites him and the costs and labor involved.

Leaving the stringers in will add some weight but reduce labor costs.

So adding composite to the excisting stringers, glassing them together and laying the deck on them is acceptable? Any concerns on strength of the original stringers since mako did not rest their decks on the stringer?

Looks great, good luck with her. The only problem besides a little weight that I could see is if the original bond of the stringers to the hull is delaminated or compromised. If there tabbing is delaminating and than you just glass over it than you still have delamination and a poor bond.

Thank you!

Please excuse my ignorance but how would I check that?

Also, how would you know if the wood has rotted you can't see it and is cover with glass?

As mentioned before there are several different ways to do stringers. I feel that some are better than others. I personally would not leave the old stringers in there. Sure it will be less work so in turn, it will be cheaper but the down side is it will add a good amount of weight. Will that be a problem? I can't give you that answer.

The last thing you want to do is spend all this time and money bringing your boat back to life only to second guess yourself on what is in my opinion cutting corners. If the guy doing the work feels like the stringers are in good enough shape to leave in place with no modification, then great. If he feels like he needs to add more material to them, to me that says they need to come out and be replaced.

I completely agree with you. The only reason he wants to add material is to raise them as the older Mako floors dod not sit on the stringers. The shop is very honest and the owner is a great guy he doesn't want me to waste money but its real hard to not do them when we are right there but then again if they are in great shape all I'm gaining is weight loss. But with removing all the wet foam and using composite material for the deck I'm already shaving off some lbs I would think.

I also always heard mako ride well due to their weight.....just thinking outloud I wonder how the ride will change with losing all this weight.

Remember, wet foam wasn't part of the original design, so losing that weight wont be an issue....by the time the extra height to the grid is added and all is said and done, your weight loss/gain will probably be neutral...

If the original stringer glass tabbing was peeling, it would be obvious, especially to the glass shop....he sounds like he knows what he's doing. She's looking good.

Thank you! Really excited. My dad bought this boat when I was 12, it's been in the family since then and he saw the heartache I went through when I was screwed by the first shop.

Can't wait to get back on the water.

Little update from this week. Still cleaning out the foam. The plan is to get the bow cut up and start figuring out the casting platform layout.

Can I ask who is doing your work and location, I have a boat I would like to get redone, and I really don't want to do it myself.

Got by the shop today and saw some progress on the stringers and bulkheads.

Went by the shop today. We got the rear bulkhead removed and marked where the new one will go. This will allow us to add a fish box between the tank and bilge. Stringers are in the process of being glassed in, so far so good!
