I've got a 2001 30 Motion O/B - love the boat. They are not a high production builder - each one is custom made. I bought mine used about 3 years ago - it came with 225 Promax outboards - not the fastest but I see 87 - 88 on GPS depending upon load, etc.
The boat really handles the chop well - much better than my last boat, a 29 Fountain. The wife loves the ride as do most who have been on my boat. They do tend to porpoise between 55 - 60 +/- if conditions are flat.
From what I have seen a 30 with 300X motors will do 105 - 106. 300 Promax boats were seeing 106 -107. Do not know what they are running with the new 300XS motors.
I believe that Motion Marine has new owners and there has been a lot of talk about a new 39 and a 40-something in the near future. Look forward to seeing them.
Thanks for the info. I am assuming those are pix of your boat? Very nice.
