Wheels for Marquipt Sea Stairs

I may need to replace the wheels on my sea stairs. Has anyone replaced the wheels on their Marquipt sea stairs from a source other than Marquipt? I don't mind paying their proud prices for the stuff they make themselves, but as I learned when I had to replace the controller on my tender crane, many of the parts on their equipment they just buy from retail suppliers and mark up 50%. For example, the winches and controllers in most of their cranes are just the same Strongarm brand stuff you can buy over the internet.

Thanks

You may be able to find an exact match thru McMaster or Harbor Freight. They have a great selection(s) at probably 1/2 the price.

They did make those difficult to outsource didn't they? They have a large diameter stem to prevent early failure IMHO.

I was wondering if I took some measurements and sent the above place a photo, if they could come up with something.

The wheels are supplied to Marquipt by Jarvis who would not sell direct, but instead referred me to Consolidated Truck and Caster in St. Louis. Tell Consoildated that you are looking for replacement stainless Marquipt wheels, and they will point you to the right replacement part. Pricing is about 60-65% of Marquipt price plus moderate shipping costs. There may be other suppliers out there, but these guys have proven themselves to be knowledgable and easy to deal with.

Thanks, guys.

Bill - please keep us updated - especially if you get part numbers and prices! Thanks.

Graingers has them in steel, about $13 a couple years ago. Still working well, and I'm in salt water.

Be careful about mixing the metals on these things. Someone put steel casters in my stairs and they did rust over time. When it came time to replace the casters because the wheels were no longer round and the bearings were shot so the casters didn't turn well (making a horrible noise 'round the clock with the slightest movement of the stairs), we could not get the casters out. We tried every magic potion we could find, and not even a torch would get them go. The metals bonded in a bad way. We eventually tore the metal on the bottom step (that's right - tore it like a sheet of paper) trying to get these rusted casters out, you can image how proud of that bottom step Marquipt is! I watched Craigslist for a ver, very long time and found a new set of stairs a couple of weeks ago for $500. Patience paid off. I got the newer style stairs with two offset handrails topped with a starboard grab rail. They are really, really nice.

Excellent Post. I picked up a crappy set a few months back on ebay and it came with rusted casters, bearings completely shot. Regret skimping given how much replacment parts cost (kind of like the boat!). I'll keep eye on this thread and try Consolidated Truck and Caster in St. Louis for sure if nothing else.

Since the sea stairs I'm putting these wheels on are pretty nice, teak treads and a nice teak handrail, I decided to bite the bullet and buy the stainless steel casters from Marquipt. Price was $54 each plus tax and shipping. Definitely pricey, but when they arrived yesterday and I opened the box I could see why. If a caster could be beautiful, these would be it. They are very heavy stainless with poly compound wheels. I'm guessing they will last a long, long time.

With regard to Ang's comment about using plain steel casters in these sea stairs, I think there will still be 'dissimilar metals" corrosion problems over time with the stainless casters since the sea stairs are aluminum. However, it shouldn't be as bad as what happens with the low cost plain steel casters. I'm dealing with that now trying to get the steel wheels out of the ladder I'm replacing. So far I've gotten one out, but the remainimg three are frozen in pretty solid. If heat doesn't work I will probably cut them off and grind out the steel pins. In fairness, though, Marquipt does recommend that the caster receivers be greased every couple of months.

(You do realize this is a 5 year old thread don't you?)

The folks in St Louis are still bang on to support this issue/thread. 36 per wheel vice 300 for a set.

This thread is still relevant and my thanks to all.

Someone is wasting everyone’s time. This was started in 2012.

You know - I still need those casters for the crappy Marquipt sea stairs I bought on ebay 5 years ago that has been sitting in my garage ever since. I should get into fine wines instead.

Previous owner never used the stairs so they are in need of replacement. I occasionally use them so might see about adding that to my spring todo list. I also have a step that the bolt has corroded away and will probably need to get drilled out.

Here is the info on Marquipt. I took the old Marquipt ones to Granger and matched them up. Much less expensive. I may have 4 old ones with black rubber wheels if interested in buying them. I switched them out because the rubber wheels left black marks on the dock.

Hi, would you by chance still have the article no on the granger order? Best regards Kristian

I’ll have to look when I get home and see if I kept the receipt

Can anyone tell me the size of the casters Marquipt uses? I have the stairway, just no casters. want to order some from other than Marquipt, but don't know what diameter the wheels are.

If memory serves me there four inches.

I just removed my wheels and the non slip tape on the steps so I'm ready to put things back together. I have a few bolts on the steps that are broken, previous owners just put a bolt and washer thru so the step rests on it when in use. I tried to drill out what's stuck in the step with no luck. Everything on the stairs is alum, why did they use SS bolts !! Seven do,you have a part number or link for the casters you got?

This happened to me: we cut the broken bolts out with a cutting wheel and grinder, built the aluminum back up with weld then re drilled and tapped the holes. Be sure to use loctite on the threads when you put the new bolts back in.
