Well the story behind this boat is pretty simple, It was handed down after sitting for roughly ten years from the original owner, so first was to get the 60 gallons of old gas defueled, carbs rebuilt , and I was off took it out a few times and just was not confident in the boat, lots of little problems, tach inop, fuel guage inop, trim inop, so on so on, so lets look at the fuel lines and so forth, well it was a slippery slope, and found lots maintenace needed to be done. Here is the progress so far, and Ill never tell who is helping me through it. youll be jealous!!
so that is the original console, first thing is to move the switch bank from the glove box to top of console. and box it in.
so then it was on to removing the console and coffin lid to get a through look at the tank and fill,vent and fuel lines.
notice the vent hose is completly compromised, the fill line was leaking, if you squezed it you could hear the spiral wire cracking in it.. Not so good 20 miles out.
here comes the best part, there was not an aluminum elbow that i have heard horror stories about, there was clean rigging slide that the fill and vent hose went to.. but... the factory used a cotton sheet to "damn" the hole so the foam would not run up to far, but from the square access port by the fill port it leaked rain water and wash water in small quanities, that got the cotton sheet wet and rotted it out, I thought I was pulling out dirty diapers! YUM!
Now to the saga of pulling the tank out, not a simple task, you can see what we used!
The chain saw made short work of the foam on the edges, applied gently you can ride the gel coat along it with out many scratches.
Even with the jack, we still had to put 4x6' and a 2x4 on same side corner of the jack and try to shear the tank from the foam on the bottom,, there is a funny story about someone flying of the side of the boat as their 2x4 snapped, youll have to hear it from him[88]
Now it was not an easy decision to pull the tank, since all I wanted to do was replace the hose, and electriacal system and get back in the water. But I figure I was so close to having it out and after reading so many tank problems we went through to pulling it out, and luckly we did. I can not imagine the problems that I would have months later with some good use on the boat.
This hole was on the fwd upper corner.
Notice the varnish stains on the bottom, with two holes.
Here is 5ft of hell!!!
So now waiting on wire order,
looking for a new tank
have to make the teak molding that the console sat on out of seaboard original was rotted,
new blue sea switch panel 8 switch with c/b's
garmin 498, and SH quest
any donations can be made to my pay pal account!! |

yep, It's alum. harbor Freight has 3 diffrent model's. Each one will jack a little higher. Get the one that goes the highest. It's a little more expensive but you will forget about that down the road when it does what you need to do. The weight of it sure had Adam suprized when he first picked it up.

so the tank was dropped off today to get duplicated off the original for the same rate as the other internet favorites. The radio cubby box is in the final stages.

| I was reading your post and how you pulled out the tank. What kind of horror problem do you hear about the gas tank in these 20c mako. I have the same model as yours and would like to know. My problem is that the gunk keeps on coming out of the tank and I have no idea where these junk are coming from. I have emptied the tank out, stuck a camera down into the tank and it looks clean to me. Anyways, I have also replaced the main door and will try and post a picture for you tomorrow. |

I'm sure you could not see to much, even with a bore scope.
The tank has baffel's in it.
Old gas sitting create's varnish in the tank. Some of that varnih can be seen it this pix, as it leaked some thru the pinhole in the bottom of the tank.
With the addition of the new corn fuel's and the problem's with them, they will help break down the varnish and you know where it will go.

| the horror story relates to some older makos, not sure exactly which year and models, i know ive seen on this site 17's have an aluminum elbow between the tank and gunwale for the fill hose to connect to. not sure on your year, this is an 83, and you can see the tunnel for the hose to slide thru nice and easy. |

Looks Great. Excellent documentation with pictures for the rest of us too. About what is the cost of the tank replacement? If you dont want to post to the forum if you dont mind sending an email to mfcolsen@yahoo.com I think I will be pulling the tank on my 73 20 in the future.

I can give you the run down.
$10 a gal to build the tank.
$60 for 1gal kit of Coal Tar epoxy.
New hose's can get expensive? New high dollar clamp's that don't cut into the rubber.
1gal kit [2gals] of 4lb density foam aprox $75 + shipping
Various fitting's, tubes of 3M101 & 3m 4200.
New fuel sending unit the type that doesn't bounce. $60
That's about it for the list for that.
Tank & hose's went in tonight. 4hrs. |

here are the updated pictures to go along with friday night progress, much easier to work at night with it being cooler. Expect to close the coffin lid and seal it Sat, then began the new electrical system
here is the tank installed with out foam and hoses yet.
here is the tank foamed in and all the hoses doubled clamped with smooth sided ss clamps.
here is a close up of the fill and vent running to the gunwale.
we did not use alot of foam on the hoses, so they wouldnt be concreted in, but workable in the future if need be.
4 lb density foam was used, it took about 80% of a one gallon kit(one gallon foam, one gallon activator for density)

well got the coffin lid sealed and screwed down.
the lid was laid in with a pretty thick bead of 3M 101 on the edge of the deck that the lid sits on. screws inserted, made sure if any oozed out to top of deck edge we cleared it out a little to make room for a top layer fillet of 3M 4200
masking off both sides of the lid, then wiping the sealent over with tongue depressor makes for a nice clean sealent job once the tape is removed

well reinstallation continues. here is the
install sequence for a Airmar B-60 transducer.
upon determining the location, it needs to be on the
right side of the hull due to prop rotation. so i decided
on moving the livewell scoop to the other side and since
the livewell hole was actually the best spot for it, it goes
here is the size of the orginal hole
here is the hole drilled out to 2 3/8 (i think)
used a block inside the hull as a pilot while hole saw was
used from outside, need a volunteer to stand on the block,
here is transducer, notice the bead of 4200, dont go crazy, unless
you like a mess
then a similar bead on the inside and screwed the nut down on the inside hand tight.
here it is all cleaned up
this weekend well began the building of the wiring cables. and cutting console for new 8 bank blue seas switch panel

| those old screen holes are not deep, they were small finishing screws almost, they did not go through the hull. but definately need to be filled so water does not get in between the laminate. |

What does the repair look like when you use the epoxy\cabosil? Does it match the gelcoat? The project looks great, by the way. Nice work.

Is that tank the same size as the orignial? It looks like it might be a smaller tank and that it doesn't have much "v" to it, but could just be the pictures.

| i dont plan on replacing the pie plates, right now i dont see the need to spend the money on the space shuttle hatch, i dont see the cost rewards to it. i dont have much in the bilge to play with. all battery's and electrical will be in console. I will be putting in new pie plates when all finished and cleaning up the boat. |

Ok, I'm amazed How did you get the thru-hull to line up so perfect? I think I would have been using a round block just so nobody would ever now it was a little cock-eyed.
Great work!

HeHe By dry fitting it and marking it with a sharpie marker.
When you lightly grind the inside of the hull where it will go, you grind half of the area which removes the mark's. Lay the block back down and remark it. them finish grinding the other half, then remark that.
The holes in the block that are bored and backfilled for the fastner's are oversize, as thing's line up perfect when you dry fit it all together, but always seem to never be exact when the sealer is added. Were talking 1/16in here usually.
To get holes drilled dead center in a lot of diffrent thing's I use these tool's and I find more use's for them all the time.

Ok, I got a little lost here, what is the sea cock bolted to? The hull or the block?

It's bolted to the block the way I've been doing them. The block is glued to the hull.
I know it show's another way to mount them in this drawing, but I don't like the extra hole's thru the hull.
The block without glass on it yet.
