Re: 18 Holiday or 21 Holiday?
Holy responses!! Thanx for all the input guys!

I've actually fished the great lakes a fair amount out of a 21ft Seaswirl that was a gas guzzler. Great boat, but the wife hated the fuel costs! It used to cost me $75 bucks an outing on average, going out about 10 miles and trolling with a 9.9 4stroke. Wat do you guys think about fuel costs with the 21? Also how loud is it? The one i'm lookin at has a fully padded dog house. And good luck with your numbers this time!

lol
I can cruise all day...put putting and 30 minute or longer runs at wide open...Never used all of my 12 gallon tank..VERY economical motors the 120's are..
As far as loud? I just have a plywood doghouse and the motor isnt loud (compared to those pesky OBs..lol) at all...Here is a simple formula
Since i don't have all the proper symbols,
I'll use % for angular velocity
$ for angular acceleration
a(B)=a(a) + $Xr(B/A) + %X[%Xr(B/A)] + 2%X(v(B/A)+a(B/A)
X stands for cross product
r is a vector and (B/A) means that the vector at point B is relative to A thus equating to velocity per decibel increase
No...they are not loud..I like the steady hummmmmmmmm of my motor anyway
