Difference between Turbo 1 and Turbo Lighting

[muchco]

What is the difference between a Turbo 1 21 pitch and and a Turbo Lightning 21 pitch? Are they both 14 1/4" in diameter? What are the bow lift characteristics of the Turbo 1 and the Turbo Lighting in comparison to a Laser II and a Raker.

Re: Difference between Turbo 1 and Turbo Lighting

This is a good question, there's no or very little info on this on the web. To complicate matters further there is now a Lightning TXP too. I think Turbo 1 is a more "overall performance" prop, at least thats what the brief description says. It would be nice to know the differences between Lightning, Lightning TXP and TXP.

Re: Difference between Turbo 1 and Turbo Lighting

Dale and Kenny have run all kind of test on this props,i have run the turbo2 and the txp the turbo 2 gave me alot of stern lift or overall lift,and the txp is a bow lifter with little stern lift,the txp is a more high performance prop i beleive and does its job at higher speeds.

Re: Difference between Turbo 1 and Turbo Lighting

Correct. The Lightnings are a larger diameter at 14 3/4" vs. 14 1/4 on the Turbo I and II. The Lightnings have much more aggressive blades and are designed for higher engine heights (X dimension).

The Lightning has a lot of bow lift. The (Lightning) TXP has more overall lift and is designed for specific types of boats like an Allison, Bullet, Stroker, Hydrostream etc. These boats have a lot of natural bow lift and require very little positive trim angle to carry the bow. The TXP worked very well on Ron's Bumble Bee.

Thanks for the response.

Dale, you and I have discussed Turbo TXP's and Lightnings on this form and via email. I am considering getting a 21 Lighting from you. A 14 1/4" X 21 Turbo 1 has come available to me. Therefore I pose this question to you.
You and I have disccused that the 14 3/4" X 21 Lightning may be best for my set up. You have recommended against the TXP, as in my application I'm looking for bow lift . In your opinion which of the three would be a better bow liffter: Turbo Lightning, Turbo 1 or Turbo 2. Or are they all comprable. What is the differnce between the Turbo 1 and Turbo 2?
From what you had mentioned earlier, I am thinking that I could probably run a heigher engine hight with the Lighting to take advantage of it's agressive blade design and diameter.
I do not have a low water pickup up and I'm not sure if I could raise my engine up enought to take advantage of the Lightnings design.
If I was to run my engine at the current height (prop shaft 4" below the lowest point of the V) or slightly higher pending water pressure, would it be correct to assume that the Lighting would pull harder (rpm wise) than a Turbo 1 or 2 of the same pitch?
I'm not trying to sell myself on the Turbo 1, but I am interested in running a Turbo prop as I have heard alot of good things about them. I just want to make the corrrect choice. I am was concerned that I may not be able to take advantage of what the Lightning has to offer without a lower water pick up. (as per the gentlman from Finland REALMASA, that bought the 21 TXP and is looking for a change)
Of the following props what do you feel would give the best bow lift in order of best to worst.

Raker (small vent holes old style) 14 1/2" X 22 pitch
Turbo 1 14 1/4" X 21 pitch
Turbo 2 14 1/4" X 21 pitch
Turbo Lightning 14 3/4 " X 21 pitch
Laser II 13 3/4 " X 21 pitch

Thanks for your time,d looking forward to your response.

Re: Difference between Turbo 1 and Turbo Lighting

Of all the props listed I've found the Lightning to have the most bow lift. Although the other choices are not bad, that's for sure. If you have the chance to try a T1 or 2, then by all means do so.

They say the difference in the Turbo I and II is that the pitch measurements were a little consertive on one or the other (can't remember which way it went). With todays progressive blades, that's not hard at all to believe. A lot depends on where you measure pitch and how much on the + or - side it is elsewhere. The earliest Rakers were like that. A 24 Raker would out perform most any other 26. But guys like to talk about bigger numbers so OMC revamped the numbers so their 24 became a 26.

The obvious difference in the T1 & 2 is one has small vent holes and the other has larger holes. Not anything to get excited about. There may be some differences in design but I've never compared the T1 & T2 back to back.

The larger diameter Lightning props really like higher X dimensions so therefore the standard Turbo's work well on a sterndrive compared to a Lightning because sterndrives tend to be mounted low and it's a real project to raise them.

During the off-season we're going to test some Lightnings and TXPs on offshore race boats. That should be interesting.

Dale,

Thanks for the response, I have this feeling that the Turbo Lightning is what I am looking for.
I will watch for your tests results from your off season testing.
I will contact you in the Spring regarding getting a Turbo Lighting in the 21 or 22 pitch range.
