    Ideal prop - 28' Landing Craft - Twin Seapro 300 AMS

    Well that makes sense. I was thinking this. But wanted to post to get other peoples opinions. Any idea why Starboard is so much different? I've read Counter Rotating drives are not as efficient so I guess this is why? Someone on another forum said they had to put a different prop on the RH...

    1988 Merc 5.7L 350mag - Powering steering shaking the boat on moderate turns @ dock.

    1988 Merc 5.7L 350mag - Powering steering shaking the boat on moderate turns @ dock.

    Hey. I bought this boat last year, the pump was low on fluid. I dono if there was a leak, but I did find the hose to the PS cooler loose (Port motor mount had oil on it, so I suspect it was leaking from this connection. So I tightened that up. It's no longer loosing fluid. The powering...

    1988 Searay 24', hole in bottom of Boat (from bunks collapsing)

    Hey all, I hate leaving threads without a conclusion. Just wanted to update it with my final repair photos :) The best part of the boat is now the part I repaired.. HAHA. I still haven't launched yet. But I've put 2 coats of Micron CSC bottom paint on it (3 coats on my repair area). First coat...

    1988 Searay 24', hole in bottom of Boat (from bunks collapsing)

    Hey all, So I got the new resin. The person at AOC recommended 1.25% if it was high 70's), so I chose 1.5% as it was 72F or so. Well it gelled and hardened as expected. When cooled back to room temp it was hard as a rock/glass. You can read it about here...

    Polyester Resin - Leftover puck cured on outside but "rubbery" on the inside

    Hey all, So the new resin arrived. Plastic World was great to deal with, the ordering guy knew all about the shelf life etc. The current Poly they sell is AOC Altek H596 unwaxed and waxed and harder is Norax MEKP-925H (9% Active Oxygen). They also sell Vinylester too. I also spoke to AOC and...

    Polyester Resin - Leftover puck cured on outside but "rubbery" on the inside

    Well I figure the resin is going in the trash or the MEKP. So I decided to do another test batch. HAHA. My new resin should be here tomorrow. All the same conditions, 3% Air Dry and around the same temp too. The 3% MEKP one got up to 268F and was very dark. 2% broken in half with a 3" cold...

    Polyester Resin - Leftover puck cured on outside but "rubbery" on the inside

    I've placed an order for some new resin made by Altek AOC H596. From another company in Toronto called Plastic World he said the products on the shelf cycle every week. So they go through a ton of this stock. Yes you are correct. I'm not testing the strength, I was trying to show the rubbery...

    Polyester Resin - Leftover puck cured on outside but "rubbery" on the inside

    This is not a double post. But my images from above have disappeared. I do understand what your saying, about measuring and I started with "drops" for the stuff on the boat. Pain in the butt, but all my tests since have been using a syringe from a vet clinic. So it was not related to the...

    Polyester Resin - Leftover puck cured on outside but "rubbery" on the inside Hey. I did all my prep work because of a hole in my boat from a railway bunk collapsing. I've finished the entire layup of CSM & 1708...

    1988 Searay 24', hole in bottom of Boat (from bunks collapsing)

    Hey. I phoned Noah's where I bought the supplies and he said it's because it's unwaxed resin?!!? I doubt it cause the outside of the pucks are quite hard and crystallized. Could it be I didn't stir enough?! But every batch?! Even the 2% batch left in the cup that seemed to cure quickly with...

    1988 Searay 24', hole in bottom of Boat (from bunks collapsing)

    Hey, It's been raining almost everyday since I ordered my supplies! Looks like I'll have a break in the rain. I finally finished all the sanding and prep work. Hardest part was sanding the grey bilge gelcoat around the hole. I can't remember what % of MEKP, I did back in 2011 for my transom...

    1989 Raw Sea Water pump 7.4L Bravo 1 - Stripped thread on pump housing

    I spent a lot of time deciding on the helicoil or timesert (which look amazing btw). There's so little "meat" in that area, I decided against drilling/tapping the hole that large. I bet it's because of the way they manufactured the bracket as it was curved in that area, plus they probably...

    1989 Raw Sea Water pump 7.4L Bravo 1 - Stripped thread on pump housing

    Hey. I have a Formula 7.4L Bravo 1, one of the engines sea water pump housing is melted (0C320740). The engine already had an aftermarket Sierra pump housing installed. So the multi-piece original housing is long gone. (Ran without water so it quickly melted) I just purchased the Merc Kit...

    1988 Searay 24', hole in bottom of Boat (from bunks collapsing)

    Well I re-measured and cut out the bad section (post above). And the damage is in a "better location". I can just cut out the bottom of the storage area. And easily access the damaged area. The damage is 5.5" from the stringer at the left and 4.5" from the part at the bottom of the photo. The...

    1988 Searay 24', hole in bottom of Boat (from bunks collapsing)

    Hi all again, Please see my new diagram. The damage is right under this red circle. I've since cut out the damage using a dremel (so I could be more precise). And the hull is .324" thick. Looks like they used 3 layers of 1708 and a few CSM layers, pretty thick! Do you still agree the above...

    1988 Searay 24', hole in bottom of Boat (from bunks collapsing)

    I went out this morning and removed the tarp (Wow these new tarps are junk, not even shedding water anymore after one winter) Anyway. The damaged can be accessed from the inside if I cut into the part circled in RED. I believe I can cut an access "hatch" in the top, but it won't leave a lot of...

    1988 Searay 24', hole in bottom of Boat (from bunks collapsing)

    Hi All, I had my Searay out last year to replace the coupler etc on my marine railway. One of bunks ripped off the supports putting a 2" angle iron through the hull. There were some words said!@#X. The photo was taken the day of, the damage has been drying on land all winter. I completely...
