Re: Is this motor enough to pull a wake boarder ?
I disagree completely with the majority of these responses (except Kyle f, who knows what he's talking about), based on my own life experience of skiing behind a very similar boat.
At about 180 pounds, I was able to get up out of deep water starts on a SLALOM ski behind a 1986 16 foot Aluminum Crestliner fishing boat (full windshield/steering/open bow style) equipped with a 70 HP Yamaha motor that topped out about 35 to 38 mph. Sounds probably very similar to what you are proposing wakeboarding behind. It dragged me quite a while, but it got me up. Anyone who knows how to ski understands that deep water slalom starts are the type of starts that need the most HP.
On 2 skis, I popped up absolutely no problem. And even Dad could get up behind it on 2 skis when he weighed probably close to 275 pounds (he dragged a whole lot though). This is the boat I learned to ski behind as a kid, and then continued to ski behind into early adulthood.
The prop made all the diff. We had a 15 pitch prop we put on for skiing, especially after I was doing deepwater slalom starts. Switched to a 17 for normal usage, and the 17 would do fine if I was on 2 skis, but it was VERY slow to get me up a slalom.
I never tried that boat on a wakeboard (wakeboarding pretty much didn't exist back then) But I wakeboard now. And I can assure you that the wakeboard is the item that needs the LEAST amount of HP to get out of the water on. It might might not even need full throttle, and certainly won't need any prop change.
It's all about surface area. The less surface area you have (slalom), the harder it is to get the ski on plane. But the more surface area you have (wakeboard), the less HP you need to get out of the water.
If you get someone know knows how to get up on a wakeboard, they will quickly prove to you that your boat will work just fine to learn behind...and then the driver will have ALL the fun. On a boat that small, a good wakeboarder cutting hard should be more capable of steering the boat just as much as the driver himself!!!!
It will be a blast. Do it.
