I only bought the little $12 bottle of CitriStrip to see how it (and me) do at stripping, but I might try some actual bottom paint remover for the next bottle, or oven cleaner, or any other home brew ideas anyone has. I’m not even supposed to have the boat in my driveway due to HOA rules so this might be sporadic. I think I need to stick with stripping and limited sanding because the paint water when wetsanding is running down the driveway and into my neighbors lawn and I’m worried about killing his grass. I need to find somewhere to pressure wash it after this coat to see what comes off.

I sanded mine off on the hull sides earlier this year and will never do it again. I mean it came out ok but it was backbreaking and the dust was literally everywhere. Shortly after, I read a thread (forgot which one) on THT of someone who borrowed their friends 4000+psi pressure washer with a sandblaster attachment. He said it came off pretty easily with no dust. Wish I saw that suggestion earlier and gave it a shot.

When I get my outboard conversion done I will be removing mine at home. Probably using a chemical and a pressure washer for starters, then sanding.

Little more CitriStrip progress. I didn’t get the second layer on thick enough I think because I was in a rush and it kinda dried out or just didn’t get as much paint. Gelcoat is showing now after a quick hit with some completely worn down 320 grit on a hand block, I need to get more sand paper today. My 6hp 2100psi pressure washer didn’t do jack squat, could be that my nozzle is shot or the pump is damaged from not draining the water enough over winter (I can put my hand in front of the tip without it hurting much), but super clean and the garden hose got more off, maybe the acid of super clean is more effective on the softer paint. Going to see if my neighbors is stronger. Started on the other side with a very thick coat, going out to strip that as soon as the sun comes up a little more.

What stripper should I try next? I read a few articles and the West marine and peel away seem to be the best. I think I’m done with CitriStrip, not overly impressed unless this thick coat does better.

Not sure where youíll be going but you can bulk buy sandpaper on eBay. Maybe save some bucks

Today’s progress. Hit it with some super clean and a brush after and it looks almost as good as the other side after 2 thin coats.

Not only the grass damage is a concern, but bottom paint is super toxic to humans.

Breathing paint dust and paint skin contact should always be prevented.

The driveway mess will get into undesired locations with unacceptable results.

This reply shows a clean / effective way to remove the paint. No fuss, no mess, zero health concern.

Good chance in Va that the person buying the boat will want it bottom painted.

I have been using drop plastic to catch what I scrape, then I use a kiddie pool to catch what I wetsand or hose or pressure wash, then dispose of it properly. I donít want to push my luck having the boat here.

I think I mentioned it before. Use PeelAway. Zero mess and it works well while you dont get the toxic dust etc to deal with.

I paid a dustless blasting company $600 and they got all the bottom paint off my 2470 pursuit. Then I had a guy paint the bottom with Interlux VC performance. Turned out pretty good! Read up on that stuff...

FYI, it's common to put on a first coat of one color followed by a different color, that way when you see the base color you know it's time for more paint.

Is that at Tournament 19? I have a 1996 Tournament 192 with rough bottom paint and an old 175hp mercury. I max out at 44mph on a good day. What prop are you running? I wonder if cleaning my bottom would help as well.

Yes it’s a 1987 tournament 19 with a 2000 FICHT 3.0 liter 200 running a 14.5x19p Viper prop. The motor was on my uncles 91 Tournament 19 with no bottom paint and would run 52 on fresh water and 54 on salt. I think that he was able to hit 6000rpm on his hull, I can only get 5800 about, so the drag is costing me RPM, which is costing me speed. My dad has a 91 tournament 19 but with a 2002 BRP FICHT 3.3 liter 200 running a 14.75 x 19 Viper prop and he can do 55 both salt and fresh water always hitting 6000 rpm, I have way more experience piloting his than when this motor was on my uncles boat. My dad’s will hit 6000rpm every time, and we did 53 a couple weeks ago with 4 adults and 2 kids and the Bimini top up on salt water, so there is definitely a difference between the 3.0 and 3.3 FICHTs. On my dads, back in 2002 when we first opened it up, it was February in CT, we had 3 of us on board and it did 57 on fresh water, at 6200rpm. Since then it’s never gone over 6000rpm so we don’t know if there’s a rev limiter or what that now works but it’s just 6000 at 55 now. My uncle now has a small block G2 200 2.6 liter on his, and with a 4 blade or 20” viper he can only get 51 on fresh water, so a new small block G2 is weaker than a 3.0. I want to see what a 20” viper would do on my dad’s 3.3, but his boat has been in NC and my uncles is in CT so we haven’t tried it yet. I only got 45 on my boat on 92 degree fresh water on lake Anna last week, but wasn’t trying super hard, and the boat was loaded with 8 people, but fresh vs salt impacts top speed on a boat not sitting on the limiter. Also your 96 has the seav2 hull which isn’t as flat as the seav1, so from what I understand it won’t be as fast.

Heres my build thread for those curious.

The boat is back at my old neighbors for the next couple weeks while I travel for work, in 2 weeks we’ll tow it to CT and Long Island for a week, and while I’m up there my brother will teach me how to wetsand, compound and polish the hull, and I’ll take another stab at bottom paint stripping. My brother restored a 1988 Mastercraft 190 and the paint and hull sanding, compounding and buffing came out awesome. He has it for sale now, but hopefully it’s not sold and I can finally ski behind it while I’m up there. I cracked a rib skiing behind my dad’s for the first time in a year the first day we were in Topsail on 3 hours of sleep (rusty and tired, never got good rhythm) which hindered my bottom paint removal that week. Here’s the video for those wanting to see why you need to tuck and roll, not extending your arm which exposes your ribs which was my fatal mistake. These FICHT evinrudes pull a skier out of the hole as well as a friends Malibu with a 350 vortec, but the wake on these Grady’s is not great for slolom.

More progress: we are in LI now and I tried my in-laws pressure washer and was able to chip away a lot of the paint with the pointiest tip they had. Then applied some CitriStrip but only waited 3 hours and it got more off. Then hand wet sanded with 40, 60, 100 or 320 depending on where I was and got more off. Going to keep at it, but man this is a crappy job.
