A good guage for tongue weight is 10% of total weight. So if you're weighing in at 1620 lbs then your tongue weight should be around 160 lbs. Put a bathroom scale under the jack wheel.

And, that was my plan pending the weight of the whole thing. So, I just got back from the more appropriate scale. The verdict: 1620 pounds. Exactly the same as the other scale to the pound. Shocking. I have to believe that the boat must weigh about 850 as set up by me. Really almost nothing in the cockpit and cabin. So that would put the trailer at about 750-800. Amazing. What to do.

I think Gary Hyde moved the axle forward on his M17 Pacific trailer because he had a tongue weight contraint on his tow vehicle. On my trailer, the spring hangers are welded to the frame, so I would have it done professionally by someone who knows how critical the axle alignment is. Too bad you can't just loosen some bolts and adjust.

This whole thing came about because of high tongue weight. There is no way I can lift the tongue on this trailer. So, hopefully this weekend I will weigh the thing again with a different scale.

Daniel:
Glessers' also have an extension.
a 'perspective' based in pushing and lifting the trailer tongue of the Glessers' trailer, without boat and with boat, and the other trailers and boat/trailers -
the trailer is lighter than 500# (one of the trailers i have that i have weighed on a scale) and lighter that an known 1800# boat/trailer combination (again weighed on a scale). so much lighter actually that the M15/trailer combo is 'next to nothing' to move from one end of the shop or parking lot to the other.
maybe your M15 has gold bars as ballast ;-)

Interesting. That is the trailer I have, the G14-1000. I do not have a spare on it. Mine has the trailer extension, which has to add like 100 pounds, since that piece of steel is a whopper.

the declared weight on the certificate of origin is based on the standard framing, axle, tires, lights, bunks and mast crutch. everything else, like a spare tire, is 'option' and not included.
the Glessers' new Pacific trailer for their M15 has a 'declared weight' of 350#. this is the G14-1000 frame.
in my work with Pacific in designing trailers they admitted to using a 'formula' to generate the trailer's weight based on stock numbers ... not actually weighing the trailer.
i haven't weighed the Glessers' trailer so i can't say what it comes in at.
