What’s this PWC trailer checklist for? Any jet ski rider who wants to avoid costly repairs & roadside breakdowns on their PWC adventures or Sea Doo tours.

With the advent of summer, the steady stream of personal watercraft trailers headed to the water gets underway. But a few don’t make it and have to pull off on the roadside while frustrated jet ski riders try to get it mobile again. Sometimes a breakdown happens by sheer chance. But more often, it’s a result of some avoidable jet ski trailer failure.

Best Practices

Prevention starts with buying a good quality jet ski trailer with built in reliability and durability. It continues with proper and regular maintenance to keep it in great shape. This includes proper winterizing and off-season storage to avoid premature structural or mechanical deterioration. At the same time, it’s also important never to exceed a jet ski trailer’s weight capacity while towing as that places undue stress on critical components that can affect its reliability. And to keep the tongue weight in the proper balance.

Murphy’s Law

However, assuming that these considerations aren’t at issue, Murphy’s Law says that things can still go wrong. Remember that every time you tow your jet ski any distance, your loaded Sea Doo trailer is exposed. It’s subject to many different road conditions, including dirt, potholes, bumps and other surface irregularities. Especially on secondary roads. What’s more, each trip typically involves a double dunking to enter and exit the water at launches. So, there is plenty of opportunity to aggravate any pre-existing mechanical jet ski trailer issues or even to start new ones.

Walk Around PWC Trailer Checklist

That’s why it makes sense to do a quick walk around inspection of your loaded jet ski trailer before embarking on a road trip for a Sea Doo tour. To make this as easy as possible, I’ve created this PWC trailer checklist. Keep it handy for future reference.

Using this jet ski checklist religiously can go a long way to saving you the considerable hassle (to say nothing of expense and disappointment) of a PWC trailer breakdown on route. The checklist assumes that you’re following best practices while towing your Sea Doo watercraft. These include properly loading and securing your jet ski on the trailer. This way, nothing can come loose that might cause a weight shift resulting in PWC trailer damage or loss of driving control.

Being Prepared For Breakdown

But even this PWC trailer checklist is no absolute guarantee of a trouble-free tow. So, if you do breakdown, your ability to remedy the situation easily may depend on having a few items handy.

These include a good pair of work gloves to protect your hands. Also, a tarp or ground sheet to keep you clean and dry if you have to kneel or lie down on the ground. And carry a lug or socket wrench properly sized for your jet ski trailer’s wheel lugs. Plus, wood blocks to chock the PWC trailer wheels from moving. Your basic toolkit should also include a pry bar and hammer, heavy duty zip ties, wire and duct tape.

Additionally, be sure to have a fully inflated spare tire mounted on your Sea Doo trailer tongue. And keep a tire pressure gauge in your vehicle. Meanwhile, for hassle-free roadside tire inflation and (PWC battery boosting), get a Jump Starter that has a handy air pump attachment.

If worse comes to worst, it pays to have a roadside assistance plan that specifically includes transporting your jet ski trailer on a flatbed to a repair location. This may not save your Sea Doo ride, but at least you’ll be able to go another day!

The PWC trailer checklist below has kept my Triton Trailer towing trouble free for years.

PWC Trailer Checklist

  • Before loading PWC’s, verify that trailer bunks are tightly fastened and properly in place.
  • Also before loading, check the winch, strap and hook to make sure all are working properly.
  • Before hooking up, grip the tow vehicle hitch to make sure it feels solid and secure.
  • Use automotive grease to lightly coat the tow vehicle ball before coupling the trailer to it.
  • Before plugging in, apply a water-resistant electrical grease to the male electrical connector from the trailer.
  • When hooking up, ensure that the trailer coupler is fully down over the tow vehicle ball and properly secured with the pin.
  • Make sure the safety chains are in good condition, criss-crossed and properly fastened to the brackets on the tow vehicle hitch.
  • Check that the electrical plug is securely connected to the outlet provided on the tow vehicle and that the wire from the trailer tongue won’t drag on the road or get pinched in transit.
  • After hooking up, eyeball your trailer tongue to make sure its sitting level (parallel) with the ground to help achieve optimum tongue weight (approx. 10% of gross trailer weight).
  • If you have a tongue jack, make sure it’s raised and secure so it doesn’t drag.
  • Check the trailer tires for proper inflation, undue tread wear and sidewall cracks (including on the inner side).
  • Confirm that the wheel lugs are all in place and tight.
  • Check the spare tire for proper inflation and good condition and that it’s securely fastened on its carrying bracket.
  • Eyeball the springs and axle for any signs of undue wear or damage.
  • Inspect all the trailer lights to make sure each is functioning properly.
  • Periodically, lube any trailer hinges or locks with a water-disbursing oil spray.
  • Check that your licence plate isn’t bent or missing from contact with a ramp.
