300R on a Mirage Jaguar Ski Racer

[Kirkmag]

No 300R for me, I love boating but not that much. When 2 strokes are totally outlawed I’ll be done.
I am an old man, I don’t have much time left anyway. It seems now days most people like top end.
I prefer quick acceleration, I don’t think the 300R is there yet, maybe some day.

Have you seen this U tube video? https://www.youtube.com/watch?v=gzDuYAF7ihU&t=5s

[Stoker boy]

Very nice, great motors for many reasons.
For me they accelerate way too slow.

[Stoker boy]

That is correct. At this point in my life, I do not care to do it anymore. That does not mean that I do not want to go fast anymore.

I hear you, the little 2.5s are not hard to rebuild but parts are expensive and it’s tedious work.
I love the acceleration you get from a 2.5 on a lightweight boat.

So what is you're compression and leak-down numbers on the 280?

Because if you are dead set on a new motor with warranty your going to have to wait till they make a 15in version, that 20in 8v will weigh as much as your boat and that weight will be crazy high.

Captain insane o lives up your way talk to him IF you need to freshen up that's a easy job for a real mechanic, you should just need rings and gaskets.

Mercury really left the little boat guys by the curb without a V6 R option

The V6 could make 250hp and weigh under 500 lbs.

I think we need to be patient for this option "I can't imagine that it won't come" being that they already have all of the tooling/parts to set one up.

So after paragraph's and paragraphs of deflection you only know of 1 STV and ZERO Mirages with with a porkchop hanging off the back. Thats quite a resumé considering he has a Mirage ... Pppffftttt

Now back to my question ....

​So lets just go with an easy one that will only require "a number" as an answer ..

How many STV or Mirage hulls have gone over 130mph with a 300r ?

Fill in the blank _ 0

I left two spots, if you need to go over 99 of them, feel free to add another ..

Dont worry I wont make you say it ... I filled it in for ya ... !!!!

Resume? How many STV/Mirage hulls have you owned?, How many hours have you logged behind the wheel of one?, I bought my first new one in 1989 and have not gone for more then a 36 month consecutive period not having one since. As for your 130 mph talk, that is a joke (there are a handful of people that have run that speed in one with any power combination and none that had a factory warranty). I never have, you never have, and never will. Kirk indicated that he wanted to be able to run the same speed/acceleration as his 280 but not deal with the maintenance/repair cost/dependability issues that he has already been faced with.

There have been V8 rude/Johnsons run on these hulls in the past but for Kirk's situation, he has a small lake that he has to turn within so C.G. will be a concern.--This is why I said that a 15" 300X or XS would be a good answer or wait for the anticipated 15" V8 four stroke.

"If you don't mind the fuel consumption, oil consumption, shake and smoke then its tuff to beat a 15" 300X. Brent ran 130 plus in his STVs powered with X motors. I ran my X and XS/X combinations for 5 years and wouldn't consider going back at this point. My next STV, "which is close to the hull size that this thread is about", will have a 15" 4.6L V-8 four stroke on it".

I guess I need to elaborate on this for you to understand: I have had to carry additional fuel with me for the last five years and burn at least 1 gallon of oil when we run for dinner to Renegades, Gators, Welaka, or Palatka and back (this has been as often as 5 times in one week period) "fuel consumption/availability was an issue for me". Depending on what route we choose to run, we have up to 5 miles of idle zone "shake/smoke and noise was an issue for me". The distance we travel is not available to most so with that being said, a 15" 300X would be a tuff combination for Kirk to beat. I also simply stated that my next STV will have a 4.6 L 15" four stroke V-8 on it for the previous mentioned issues that I want to avoid but still have the performance that I desire.

My engine is running just fine at the moment. It was rebuilt recently for the second time in about 3 years. The first time it had black gunk coating the screens in front of the injectors causing it to run lean. The black gunk thought to be from Ethanol melting the fuel lines. All of the lines have since been replaced. The second time the gasket under the powerhead failed and leaked water into one of the cylinders. I have also gone through 2 lower units in the 7 years I have owned it. I put very low hours on it in the short Michigan summers. I am running the engine up to about 8200 RPM with the way I have it propped. The 300R 20" weighs about 200 pounds more than my 280. I might give it another year and see if the 15" nears availability.

I have built enough rear engine dragster's to know that the first ones started out at around 215" then went to 225" because that's about it for a 24' trailer. Usually guys couldn't swing a new car and a trailer at the same time. I had a 509" that made just under 900 hp .. it was a handful. I sold the car and built a 240" wheelbase , and then offered only 240 to 275" long cars. Why .. cuz the more power you make the longer car you need. I asked Jack when he was here, and Mike M. over the phone , why their boats didn't grow over the years with the inception of bigger power .. ???
I won't put words in peoples mouths .. you can ask yourself when you pop for your next one ...
The 4 or 5 times I started to pull the trigger on buying an STV , I was talked out of it by guys who have been 130 mph in them , both black and white motors .. people whom I trust.
BTW, how many times you been 200+ in the quarter mile .. _ _ _
I won't say you never will ... Only a fool would say what another man may or may not do in the future ...
If you go back and read again .. I was speaking about a resume' of STV / Mirage boats with 300r combo's .. not people. But if it's good for you to let it out, I have wide shoulders ...

Let me understand a little better, shake smoke and noise ... LMAO .. Shake is feedback that lets you know it's running . Smoke keep's the skeeters away, specially in the swamp where you guys like to go .. NOISE .. really you are an old **** Even at my age ... IT'S STILL MUSIC ..

There is this marvelous new invention ( I got one 52 years ago) called a ratio~rite.
Use it to measure out 2 oz per gallon of gas . This can will do 64 gallons ... so if it takes you more that a 55 gallon drum to get home .. better buy a two pack

That's great get another season out of it, Merc should have them available this time next year, did you see pictures of Joe's new ride, much larger flys over ruff water and still fast, sure you could get a good price for your present set up and move up

These can now be built lighter now.

You are right, pavement pounder experience (which I know you have tons of knowledge and experience with) is closer in comparison to an STV with 3L motors or the one that I drove with a 300R to what this thread is supposed to be about. "lets at least keep water involved in the discussion". Let me know when you go out for 130 pass in your new STV and then I will join you with my upcoming project. -Until then I will stick with my prediction. 130 mph use was your example not mine-I have no desire and very few have ever seen it "never with stock warrantied power". I am not a sandbar racer but rather go to a destination and maybe do a little spirited running the the guys that pull up next to us. Yes, at 50 I am an old fart to many but in idle zones I prefer to hear my stereo and not hear her complaints out how smokey things are (thank you Mercury Racing for solving these small life issues").

There is no place with more people willing and desiring to run then LOTO. You have a free place to stay and will have a nice building to park your boat and motorhome in very soon. Again, let me know when you are ready to come out. I am going to the river right now with my Allison "Astor lunch with Z06 man".

CHAZ are both your motors on your personal boat still blown up?

You need to get out and smell the dead fish and get some vitamin D

Your getting Cranky

His boat looks great! I would love it on bigger water but too much mass to accelerate for my needs.

Are these your words ...
Naturally, I hate to be the bearer of bad news .. but you set the bar at 130 . Go head, find where I mentioned it before the above post ...

You also spoke of acceleration this, acceleration that .. how many time about the 300r in the last year .... I only asked how many time you been to the duce in the quarter .. to see where your yardstick is based from ...
If it has dwindled to the point where you think a 300r is quick and fast ... I feel for ya ..

Well , we are actually talking about a Mirage ... where there are none , or no one has spoken up about ... out there .
And if you drove the one and only 300r STV , give us a handling report .. you had to throw it into a few 3G turns . Mark off a quarter or 800' and bust out some stop watch's . Run it with the tongue hangin out with a 40" wheel ... How bout how many gallons of swamp water you take over the stern when coming off plane ... How does it run in the Indian river on an average day ... !
No none of that .. just look at me .. whippeee .. a new quiet porkchop ..

At least Davie use to meet me at Jensen causeway and we'd run to the powerlines . Then from the powerlines to Ft. Pierce . (bout 25 miles total) You expect me to go to pert near the Georgia line .. or Middle Missouri .. to go for a little romp ...

No I usually blow them up one at a time ...

Busy time of the year for me . Lots of stuff to deliver ... till like February - March

That is a huge motor, I would have to wait for a 15 inch just for the looks alone.
