Mantus 45 Problem

[powsmias]

hi all,
assembling a mantus 45 yesterday to ready boat. Bolt size not matching the drilled holes and am sure it gets straightened out. In the meantime If anyone on this forum owns one would appreciate knowing what size wrench they used for their 45. I don't want the company to send a smaller bolt if they messed up and drilled incorrectly. Thanx in advance

Have you tried contacting Mantus? My experience they are very responsive to customer service and any questions.

When my Mantus 65 was shipped to me the shipper managed to damage the pallet and packing (which was very well done by Mantus, not their fault at all) which tore apart the package holding the bolts losing several. A message to Mantus resulted in a complete new set of bolts and nuts sent the next day.

I did and still need to give them some info, my concern is they send smaller bolts to cover the mess, if a mess, and smaller bolts means a weak point. they want to know size of holes drilled and before i give them that info i want to know what size should they be? just covering bases.. thanx

If you feel the need, but my experience, these guys are highly ethical and I doubt very seriously they would BS you on the proper bolts for the anchor. If they screwed up the holes they would own up to it and make it right.

If you are that concerned they will try to trick you on this, call anonymously and ask about bolt size without disclosing your issue.

Thanks for this, got a private message that correct size is 3/4, your info different. they sent 15/16.... so way off somewhere. the bolts i have would seem about the right size if they had to tap it but that not in equation. Skipmak thanx thought about that but my pool room mentality kicked in and always on guard for someone "gettin over on ya" mindset. (apologies to mantus) hoping my thinkin is human nature. thank you all

All done and with class by mfr.. thank you all.. love this site, saved me hours on everything boating,

Bolt size is the diameter of the shaft - The head size is different. Hopefully you are not confusing the 2 measurements.

On another note after lubing up the bolts very well you just need to tighten them till the lock washer compresses all the way. A little more than hand tight.

There are specs for torque dry or lubed. I did some measurements and found that the Mantus recommendation (as stated above) gives a torque very close to the specs.

Umm, any chance you could explain? The bolt sizes posted above are correct from Mantus' website.

I did notice the sizes I posted above are completely screwed up when viewed on an iPhone using the app, but appear correctly when viewed on the web using a browser.

I guess I still don't understand. Is the correct size bolt for the 45, 1/2" or 3/4"? (Or 15/16"?)

Don't know. Only Greg or the OP can let us know if the posted sizes are correct. However I can't imagine a 3/4" bolt is correct, that's a huge bolt!!

i have the 25lb that i purchased last month. one thing i noted while assembling was that the shank and fluke bolt holes were off somewhat on alignment. the bolts seemed to be undersized? also only one drain hole on the roll bar.

[sailorchic34]

I have a 45# Mantus and it came with 1/2" bolts. Note that is the BOLT diameter and not the nut / spanner size.

[Privleoplag]

OP asked what size wrench.. and as someone else stated, a 1/2 inch bolt almost always takes a 3/4 inch wrench.

What size wrench means nothing when talking the size of the bolt because there is no consistency. Then there's the darn bolts that usually take a 5/8ths on one side and an 11/16th on the other...
