A few weeks ago we ordered a 2010 Harris Cruiser 20' with 50hp Merc 4 stroke and 25" toons. Our original intent was crusing and fishing a little, maybe letting the kids 9 and 11 tube a little. After reading on this board it looks like the 50hp will work for tubing for the kids but maybe not for long and would be kind of lame for the adults, so my question.
If I am not tubing my preference is a efficient gas sipping cruise, speed is of no concern to me. From what I understand this boat will do about 17 or 18 with avg load and 4 people is that correct?
However when tubing with Avg load this may only do 14-15 is that correct?
If I upgrade to the 90hp (max allowed for boat) will there be much difference in speed, I am estimating avg load 21-22 and tubing 18-19 is that low or will it be more?
I know eveyone says always go for the most motor you can afford and the boat will allow, but unless I am tubing I don't care about the power. Also if the upgrade will not make much of a noticeable difference for tubing then I don't want to spend the extra money and I will just be content with what I have. I am really struggling to know if there will be a difference worth the money. I mean if I go with the 90 will adults tube and be fun, or will it still be fairly lame? The upgrade will cost $1750 to do now before I take the boat, do you think it will add the entertainment value for me? Will I notice the gas difference crusing? Does $1750 sound right or a little high for the upgrade?
Hope this isn't too long, thanks in advance for any advice!
