Adding axle
I am considering making my single axle trailer into a tandem axle. Any pros or cons about doing it. How about info on where to place axles on trailer? Thanks in advance for any info.

A little evolved but should give you a good reference. Good luck.

I pull my boat quite a distance sometimes and I would feel more at ease with tandem axles. I have had bearings go out on a single axle before and you are stranded. At least with a tandem you can ease it on home, maybe.Originally Posted by Mbsbeek
This is the trailer that come with the boat.

Then keep a spare hub loaded with bearings. Unless you let one go way too long and it chews up the spindle, takes about the same amount of time to swap a hub as it does to chain up an axle.
To convert to tandems, you're looking at cutting off all the current mounts and welding on new ones to get the axles centered properly, plus the expense of a whole new axle assembly, wheels and tires, springs, fenders, hardware, etc.

Whe.n pushing a trailer by hand it is almost impossible to turn a tandem axle trailer

Thanks for the feedback. any more input?
Before I add any input as to the tandem vs single, I would like to know what type of boat and what the boat and gear weighs and what tire size the trailer has now.
Trailers supplied with boats is one of the areas dealers can work on price and most trailers are just on the fringe of overload unless a custom trailer was specced for that boat.
Just adding an axle or going to a tandem may be too stiff for the load so let's start at the beginning, where the rubber meets the road.

Is that the total loaded or just hull weight?Blue wave 189 center console around 1500#
Keepin mind the hull weight+motor+ fuel+batteries +accessories etc and the weight of the trailer itself.
Looked at their web page and smallest hull weights I could find ranged between 1395 & 1500.
Either way it would seem that a tandem axle may be overkill for that weight class.
Kind of a rule of thumb is under 3000lb is a single and over is getting into a tandem due to tire weight capacity.
Considering at 2000lbs total with weight of trailer added, each wheel on a tandem would only carry 500lbs.
Most tandem trailers I have owned had 3500 -4000lb axles so each wheel had a capacity of 1750 -2000lbs.
A tandem may bounce too much unless the trailer manuf. adjusted the spring capacity accordingly.
Also keep in mind a wider wheel base trailer is much more stable when towing.
Any numbers, weight/axle capacity ratings visible on your current trailer?
Changing a single to a tandem maybe be a possibility but it is a balancing act best left to the manufacturers.
If you decide on a tandem, I would just get a new trailer specced for that boat and sell the single axle as you would be money ahead and much happier in the way it tows long distance.
Just went through this last year in deciding on a new trailer for my 20 yr old 17.5 ft alum. Sylvan(total loaded weight about 2500lbs) for long trips (1000-1200 miles@way) to Canada.
Had a Trailmaster 4" tube(heavier than 3" tube), 96" wide, with a Dexter 4000lb EZ lube axle and Goodyear Endurance D rated tires for weight and a 87mph speed rating built.
Last year while taking a turn driving, a friend commented on how well the new trailer and boat towed and tracked behind the truck like his tandem trailer.
Feel free to ask any questions and Good Luck on your decision.
