Gotta question for the Triton owners. Have a friend that has a 2002 189 with a 175 hpdi yammy and an 8 hp kicker. He's running a 3 blade/21 pitch yammy prop. When he has the boat loaded for bear he has a poor hole shot and only runs about 52 mph/gps and he's running 5650 rpm, to many rpm . His dealer told him to just back off on the throttle so he's not running to many R's. Which he doesn't like or agree with. Before this his dealer set him up with a 23 tempest. He had a VERY POOR hole shot at best. Once he did get it on plane he'd run 56 or so which he was happy with but was only running 5000 rpm. Anybody out there got any ideas. His dealer told him he might wanna look at installing a whale-tail or some thing to that effect. Thanks in advance to all that reply. Hutch

The 189 and 205 both have a LOT of weight in the stern, which makes good hole shot difficult. The best prop to get that hull out of the hole would be a high five. While this is the best prop, it may not be enough to acheive the performance he desires. He may want ot go to a stabilizer as you mentioned.
see if his dealer will let him try a 4blade 27in pitch raker
sometimes they come out with smaller diamater with higher pitch I dont care what the dealer will say Iv experianced cavitation,low speed,and low power. with smaller diamater.

except that I believe a raker is a 3 blade, omc hub. And a 27 will kill his rpms.
Husky,
I've had a 205 since 1999 and have never had a problem with hole shot. In fact, there are very few bass boats that can take me out of the hole. To say all 189's and 205's have a poor hole shot is a gross generalization.I'm running a 225 VMax with a 23 Tempest plus and get great hole shot and top end as well.

Jon,
I did not say all Triton 205 and 289 have poor hole shot. I said the weight distribution makes it difficult to get good hole shot.
I am glad yours operates fine. I am sure the extra torque of the big block 225 has a lot to do with it, along with the extra 2 feet of length over the 189.
Most reviews of the riton walleye boats note sluggish holeshot, as well as the dealer where my friend is a service manager.
The 189, being 2 feet shorter, translating to a greater percentage of weight in the stern, smaller max hp (cubic inches and torque) has even more of a problem. I was just stating what others have experiences, did not mean for it to be a blanket statement.
Have you tried a small hub trophy? This is a 4 blade so it should help your hole shot. You can get a ring that fits the prop so the exhaust is still forced through the center. I'd try the 23 pitch. The overall diameter is smaller so you should get a few more rpm's. I have also seen guys run without the ring and have excellent results.

Right on Jeff. I know alot of Triton owners and all run the 4-blade Trophy. All 189's should have a Whale Tail. They help alot. With this prop you should run just a hair under 5600 and should be in the 56 mph range.

5650 is EXCELLENT. Right where they want those engines running.
Hutch, I'm sure you know Glen and Mark as well as I do, I sold this boat and set it up for them. They should have went with to 200 HPDI. I think they are over loading the boat at the stern and they expect to have a rocket hole shot with both well's full and two to three persons on board. That will be tuff to do. The HPDI and Optimax just don't have the lowend torque the EFI's do. We have one of the best prop guy's in central Illinios so with his help we will make them happy. Thank's R,P,
I have an Offshore Renegade 19 on my 205 Hutch, and my hole-shots are envied by a lot of bass boat owners. Im not an expert on props, but the dealer I got my boat from thought this was a good prop for mine. I run mid-sixties at WOT and 5600rpms, and wouldnt change a thing. And carrying a 9.9 4-stroke kicker. Dont have a jackplate, which they say would get me a couple more mph. Im running a 225 "JOHNSON" that I really like. Likes its gas, and a little cold-hearted, but (knock on wood) it hasnt hesitated to get me where Im going. By the way, what is max hp rating for the 189?

Send an email or call Rich Boger - www.bogerprops.com He is widely recognized as a prop guru. He can also take your stock prop which is right on for rpm's and give it the tweaks it needs to get your holeshot where you want it.

Hey 205 dream on about your top speed,with the pitch prop you gave and the rpm's given you would be lucky to hit mid 50's.
Sorry Rvrrat and others, eat your heart out. :-) Unless my glasses need changed or my dashboard gauges need changed, thats what Im reading. Dont believe you boys ever rode in one. Come on down to the Ohio River and I'll make believers out of ya. :-)
no way

205...when I read your post, the first thing I thought of is your reading the dash guages and not reading a gps reading. My ranger in dash speedometer reads 64 mph and my gps is 57 to 58 speed across ground. Like said earlier, the rpms and speed you said is not mechanically possible. This isn't meant to put you down, just think you are making a mistake in your information.
Oh, almost forgot. You guys coming down for a ride will need to bring own lifejacket, and a neck-brace in case of whiplash! :-)

205,
Better check those gauges.!
I ran the numbers , 5600rpm, 19 pitch, 1.85 gearing and came up with a theoretical top end of 57 miles per hour with ZERO SLIP at the prop.
Sorry to burst your bubble, but the laws of physics prevail....
In all actuality, You would need a negative 5 percent (-5%) slip factor, of course meaning that you are not only not in the water, but you are in outer space. Now, I think that with your motor and the right prop you could get to the low 60's in that boat, it is a fast hull, but it IS NOT going to happen with a 19 pitch prop with those rpm's. As far a whiplash...., they all do that if you spear a wave at 54 mph.

Ryno,
You're right on. With my yammie VMax 225 and a Tempest 23 Plus Prop and a jackplate I run GPS 63-64 mph on a light chop .The Triton factory said the Tempest 23 plus prop gives you the best overall performance.I would think a 19" prop would be too small for this rig.
First of all, sorry Hutch for turning you're thread into bash fest. Havent hurry from any of the top guns. But sounds like a lot of guys should be getting rid of their dogs.:-) Just ask Paul Reiger what these boats should be doing. What sold me on the Triton in the first place started right here at walleyecentral and a little chat. According to Reiger, they tested this boat at 75 gps mph, with a stock Merc 225 efi(no jackplate) and a 24 trophy. Still say Mines faster than Yours! http://www.walleyecentral.com/chat-triton.htm
And I say that if I bring a boat that will do 58mph, gps, I will still be ahead of you, and your setup. As far as Mr. Reigers? chat, He would need to be spinning some 6500 rpms on that "stock" efi with a 24 pitch prop to get that speed. You still don't get it,...But I bet Hutch does.

I got the boat (2002 189dcf with 200 efi Merc and Tempest 23 Plus with Detweiler manual jackplate) and it had a very poor holeshot. After switching to a High-Five, I get a very good holeshot and a speedometer top-end of 60 mph with about a 1/4 trim and about 5200 rpm.
About a month ago, a Triton rep called me from Tennessee to find out how I liked the boat. I told him about the poor holeshot with the Tempest 23 Plus, and he told me that he had had many such complaints.His explanation was that the 2002 Merc 200 EFI had a longer lower end than previous models and that that extra drag was the source of the problem. He added that Merc had shortened the lower end for 2003. He also said that most of the other 2002 189 owners with Merc 200 efi's had solved the problem the way I had--by switching to a High-Five. I spoke with Rich Boger about this and he thought it sounded plausible; he agreed that the High-Five was a reasonable solution, but suspected that a four-blade Trophy might be better. I'm satisfied with the High-Five at this point and think I'll keep things where they are. Most times, the water I fish is too rough to get anywhere near WOT anyway! Jack R
