08 60hp merc efi 4 stroke planing


shimano19

Recommended Posts

a close friend has a 16 foot smoker craft with the four stroke merc and the thing wont plane with one person in the boat...

 

once it does get on plane it bounces around and feels like you are getting in a car wreck every time it hits a ripple...not a fan at all.

Tell him to check the Prop he has installed - going to guess it has too much Pitch for the motor/boat setup. When I bought my Smokercraft, it had a 23P prop installed - what I found out is that Marina's will often take the original prop off (or never got it on the sale) and will just install what they "think" will work.

 

So Plane took forever, top speed was great, but it would porpoise all over the place, and as you describe at the slightest ripple - generally speaking could not run it WOT. I was going to go smart tabs, etc. - but decided first to properly size the Prop for the Motor and Boat.

Big difference - does not hop around at all.

I would love to make the suggestion, but id feel bad talking negatively about the boat. probably best if i kept my thoughts to myself. its their first family boat, so im pretty sure they just dont know any better.

 

Exact same problem though, with 3 of us in the boat we have to do all sorts of maneuvering just to get the nose to sit down.

Loaded up with 3 guys and gear? I think when the OP is by himself the boat is fine. It's only when it's loaded that it's a problem.

Tillers plane much faster from what I've seen

 

My 16' lund with 50 hp planes with 3 of us and gear in a respectable time... I would never say she jumps outta the water but I'm on plane in 5-10 seconds I'd guess

I haven't had that experience...........it's more like a boat/motor/prop/ with proper weight distribution works best. If the boat is under powered nothing is going to change that problem unless you remove the lard butt in the rear of the boat.......LOL

I have a Princecraft 164S with that same motor: 2 guys no problem, 3 guys a littls slow to get up, 4 guys takes it's time. My live well is in the front so if I have 3 or 4 guys in the boat I just pump the live well full and that extra weight in the front makes a huge differance. My boat is also rated for a 75 but I am quite happy with the 60 on it!

Ok, I'm no expert on 16' aluminum boats so I have a question...what is the boat's capacity plate indicate for # of people and weight at the max housepower? Just my opinion but if I spent $15K - $25K on a boat and couldn't take two buddies out, I'd be unhappy. I certainly realize hp choices play a huge part and this may be the issue here, but many of the subsequent posts are surprising.
