If you do decide to purchase
this boat and then a truck to pull it with, be very careful if you want a Ford F 550 with the Powerstroke (International) diesel
I could be off a year or two on this but I know for a fact the F550 in 99 used the auto trans from the F150, with mods.
It isn't a good application.
I have a friend who owns one and pulls a 44" race
car trailer. Max wt of the trailer and contents is less than 9K #.
WILL and DOES burn up, and in many cases, literally.
At 33k it went up in smoke.
The dealer told him they were aware of the problem and replaced everything at no charge.
Ford chose not to do a recall
but replace at their cost on an as needed basis.
That was two transmissions ago.
The trans fluid MUST be changed IIRC every 3k miles, and it holds 22 qts, IIRC.
He hasn't replaced the truck because he might put 5k a year on it.
is a pig, even pulling 8k#. He got a remap of the ECU and it helped a lot. The engine
doesn't almost die between shifts.
It has lots more power and gets 17mpg.
It is still a dog.
If it had either the manual trans or was a newer model (2001 up, IIRC) they could have put in a more aggressive map.
IMO for this job I would get a truck just a bit heavier than a F550, such as a Top Kick (GMC-used only as an example) or one from one of the other brands in that size. That boat and trailer is too close to the F550s capacities for me, even with the newer models.
Good luck with any choice you make.
