Yes. I am assembling at shore.
Why does that matter in choosing a motor ? 9.9's are very light weight , even older ones . You can carry them with one hand and 15's are usually the same size , made from the same block . I used to pack around a much heavier older 80's 20 hp evinrude long leg and put it onto a boat at the shore(which is doable for a young guy, but 20's are way heavier) . No biggie with a 15 or 9.9 .
And they are NOT alot of maintenance if you get a 2 stroke . Pretty much all you need to do is change the oil in the leg about once season , which involves only taking out a drain plug and a filler plug , very easily done , much easier than an oil change on a car . Change spark plugs when needed (easy) , grease moving parts every so often and that's about it .
If you opt for for 9.9 or 15 you won't regret it like you will with a 5 or less .
