| I have decide that I will be going with the 620, My question is kicker size, I have a great package deal for one with only a 8HP kicker. Is this big enough for trolling spinner baits at 5mph or will I need a bigger kicker.
Thanks

| Hi Troy,
I'd rethink the 8 HP kicker. Not so much because of the HP(the 620 is a BIG boat), but because of the alternator output. If the 8 HP is a Yamaha, the alternator output is 5 amps. The 9.9 HP doubles that to 10 amps. The Merc 9.9 HP is also 10 amps. This extra output will come in handy during long trolling sessions to maintain your cranking battery, which will be powering the livewell, depthfinders, GPS, Radios, lights, and other accesories.
I am not sure how hard the 8 HP will have to work to push the 620 up to 5-6 MPH. Hopefully, you'll get some input from a 620 owner. But perhaps there isn't one out there with a 8 HP kicker.
Hope this helps.
Just out of curiosity, what is your package, and how great is it, pricewise.
Good luck,
Shep |

| I noticed that a number of dealers where showing a 8hp 4-stroke Yamaha as a kicker on a bunch of different brands of large fishing boats at the Minneapolis boat show. I asked a couple of them why there where showing an 8 horse on large (19-20) boats as I didn't think the motor would move the boat very fast or at all in a wind. The answer they can back with was that this was a new model for Yamaha and they wanted to get it out in the market. When I asked them how it would perform they didn't have a clue. I doubt that an 8-horse will push a 620 much past 4-5 mph on a calm day.
I had a 9.9 2-stroke (Evinrude) on a 219 Stratos (a smaller boat than the 620), that at WOT would push the boat at 5.5 mph (GPS). I now have a 15hp 2-stroke (Merc) on a 205 Triton, which is about the same size boat as the 620 that I have had up almost 7 mph (down wind). Most of the time I'm running about 6.5 at WOT on a calm day. I've also used a 9.9 4-stroke on the big Targa (around 20' I think), that I had to run at WOT to get the speed I wanted to fall troll on the LOTWs, as I recall I was getting in the 4.5-5 mph speed with the 9.9 on the Targa.
I'd go to a 15 if you need to go in the 5.5-6.5mph range to do what you want as far as trolling speed goes.
The other option is to use the big motor, the ones I've used will troll down to about 3.5 mph, and of course you can speed up. Only use the 8 hp for walleyes or if you really want to go slow, or if you need to get home.

| Doug,
I think the Yammy you mention is the T8 High Thrust. This is a motor designed for being a kicker, and more than likely for walleye types(<2.5 MPH). It is the only small HP motor available with power tilt and trim. Did you notice the size of the prop? It looks pretty large compared to a regular 8 HP prop. I think the gearing is also different. I doubt it would push a 620 up to 5-6. As a new product, I would bet they will come out with larger versions in the next year or two. Look for other brands to follow suit.
BTW, I saw a "show" price of $2995 for this motor, with a Panther steer, and some other stuff in Milwaukee last week. A little steep, me thinks.

| The T8 4-stroke will be quite enough to push your 620 for trolling. We've even put them on 16ft pontoons. The high thrust motor has as much push as a 10hp motor. The T9.9 is the next biggest and a 15 would be overkill. A 15 isn't needed as a kicker any more with the new high thrust motors. |

| Terry:
And exactly how fast did the 8hp high thrust motor (that hasn't been on the market except for this year) push the 16ft pontoon? This guy is looking for straight answers not a sales pitch!
