As far as gallons per hour. I get about 6-7 if I am working it constantly. If wakeboarding and the person falls a lot, I use less gallons per engine hour. Aggressive tubing on a tube that doesn't throw people off, I use a little more.

I will help remove the doubt for you. That is exactly what I was told to a very specific question on hp. EXACTLY. I'm sharing the info I received on all items from them. Nothing added nothing exagerated! NOTHING. Once again, The Mp engine appears to be a good engine so far and I believe everyone seems to agree on that. By the way, ford had to recall their mustangs because they did not meet the published hp. By how much I do not remember, but that was the case.
Thank You for the 3 web sites for the engines.. much appreciated!

Which of the three makes the GM Votec 6.0 used in Tiges?

[CessnaCaptain]

It would seem........

1. That torque and the curve/ the rpm curve and torque produced thruout it's ranges would be signifigant since we are essentially twisting a prop. I am all for letting acme help my goals but still want to know some thing for myself.

2. Wrangler, it is hard to tell but you probably have a MP motor. It looks as though Indmar keeps it's 6.0 for signature usage & if you had a PCM it would be obvious by the red cover.

Let me start by saying that I am NOT an engine person! Let me repeat, I am NOT an engine person. And all of the service techs at the dealers I've worked with would laugh and agree with me. :-)

One piece of information that I can pass along is that when I used to work with a different brand of inboard boats that used Indmar motors, I had several customers who asked for similar information that you guys are asking for, namely the torque curves. My factory rep at the time told me that Indmar would not post torque curves because a competitor could take that torque curve and basically build an engine backwards based on the information and eventually build an identical engine. I was also told that by MerCruiser. By NOT publicizing their torque curves, it helped them protect their designs.

There are alot of guys on the message boards who are more knowledgeable than I am on engines, so you can probably tell me if this was a legitimate reason.

Thanks,

Let's keep the engines in perspective. Indmar, Merc, Volvo, PCM and Marine Power all purchase their engines from the same supplier. That company is GM Powertrain. After these companies receive their engines they all apply their marine applications to the engines and sell them to their manufacturers. There are differences in the engines relative to the marine applications but the long blocks are the same. Marine Power, Volvo and PCM use a different intake manifold that is purchased seperately but they are GM intakes. All of the manufacturers have the ability to make program adjustments to the ECMs. In the case of Marine Power their patented exhaust manifold allows them to achieve better performance than the other competitors. Indmar uses different intake manifolds and they do make a few other changes to their engines. Remeber that they have to sell and convince three different manufacturers that they are getting the best engine. Additionally, you will not find any published information on Indmar torque and horse power. It is probably for this reason. Marine Power chooses not to publish theirs either. I would not be concerned in the least about Marine Power. The fact that 90% of the Tiges that leave the factory with Marine Power engines is based on performance, reliability, preventative maintenance features, warranty and customer service. If you perfer PCM or Merc we can provide them to you also. Take a look at the performance test results in waterski mag and boattest.com and others. Tige is using the 5.7 340 in all of their boats. Other manufacturers are using 8.1s and 6.2s and they are not able to achieve our level of performance. Our performance is two fold, advanced hull technology and improved engine performance. Sorry for the long post. Hey, the sun finally came out here in Abilene. I gotta go!!

Thanks Terry...

It is nice to know not only are the guys at the top listening but able to comment back to an eager audience of Tige' owners and fans.

After reading, re-reading, and thinking about your post and how it relates to my concerns I have came to this.

I am interested in knowing the performance differences of these motors on a Tige' 24 ve. It would be nice to here a laymans perception of the differences, for me it would be between PCM & MP, in the performance and application differences on both motors in both categories of HP 340/335-380/375 with stantard proping. The performance data from an apples to apples comparison would be a valuable tool for your prospective buyers.

Is This Possible,

CC,

We seldom take boats out and and administer performance tests after the mags test them like crazy. We did put the engine in all of our boats that we knew would provide us with the best results. The one drawback to the PCM would be the exhaust system. Their exhaust manifolds do not allow us to put the cross over muffler system on it so it is not as quiet. If you have it narrowed down to the PCM or the Marine Power you will not make a bad choice. You will pay a little more for the PCM however. If you want to call me at the office on Monday I will discuss the engine selections further with you.

for reference on your question regarding torque, go to www.marinepowerusa.com/eng%20specs/5.7.htm scroll all the way down and you will see the torque rating published for the 5.7l mpi engine from Marinepower. I believe its 358 ft lbs. for the
the one they have rated 325hp mpi. This engine falls into the hp rating they list in their 2004 manual which shows a range of between 325 and 335 hp. The manual that comes with the 05 boat shows these hp ratings, however the hp for the 05 boat is 340 as listed on the engine cover and TIGE sales brochure. You can use this as a guide to better approximate as to what you may expect. Hope the details in this site I provided will help you.

PCM also has a published rating on their 5.7L 330hp engine. Take a look at the torque value they provide. You now have a comparison. Go the the following site:
www.pcmengines.com/57.html

I also found torque ratings for you on the various indmar engines
go to the folowing: www.malibuboats.com/engine.aspx
you now have three different suppliers with their ratings that you can compare.
I hope this helps you.

If the information on those sites is correct the PCM motor would have about 20% more torque than the MP. (MP-358lbs and PCM - 430lbs) thats quite a difference.

While not as technically in depth as some of the discussions going on in this thread, we really struggled with the engine choice as well. The primary driver for us was "what we were used to seeing" and familiar with. Friends with tow boats have a variety of engines including PCM and Indmar. I ended up with the Marine Power motor from Tige and haven't had one day so far of being unhappy with that choice. So far so good... It runs strong, does everything we ask it to and hasn't given us a lick of trouble in our relatively short romance... Just one more reporters opinion...

Scottty,

I have a great idea! Let's take a 24ve out to Mead with the stock 340 MP and it will ROCK your world. We did a demo Sunday with seven people in the boat and the customer was blown away...

I, as many other Tige' dealers, sold nothing but Mercruiser engines for years. We had some issues during that time that Mercruiser, (to their credit), took care of. The fact that Mercruiser was willing to warrant their powertrains for just one year was a sore subject for many of us customer service-driven dealers. Many people put just 30 or 40 hours on their boats in a season. That equates to a 3 or 4 thousand mile warranty for those customers! When we tried to get the warranty lengthened our requests fell on deaf ears.

I have since become good friends with Eddie from Marine Power. I can tell you he is totally committed to providing the strongest engines in the industry. His company DOMINATES the aluminum jet boat market in the pacific northwest and that customer is really hard on equipment.

Since I switched over to Marine Power the silence from my service customers has been DEAFENING!

Give me a call soon!

Matt
