any idea the elevation? thanks a lot.
sorry to ask this late in the thread, but for a stock 49 ci motor, in racing, should use a 059 jet? is that sea level? also, 19 degrees tdc? thanks a lot.
Hey, I remember reading that the hot setup on these old omc powerheads is to run 19tdc and a .059 jet size. first off, is this correct? secondly, is this sea level jet size? I just need to make...
yeah, but they do make systems that bolt the end of the cable to the boat, within the splashwell area, and then the cable end attaches to the front of the motor. I would google "attaching boat...
I have had both single and dual ride guide set ups on my hydrostreams. to be honest, a single steer, set up properly does fine for me on a 15 foot with an inline 6 or a bubble back running mid 70s. ...
I have a 1985 115 (crossflow, bubble back) and the power packs are labeled "CD4 582811 OA 1U4" any idea if these have a rev-limiter? I am hoping not. if they do, where would I now get new packs...
Anybody know the best way (financially) to have a boat sent from Minnesota to Maryland? it is a 15 foot boat, total weight with trailer about 1,100 pounds.
call my cell if you have any help on...
some of you know, i just got my first old merc, always had johnson and evinrude. took it out tonight, and the pisser would pump a little, but then just drip. the water wasn't real hot, and i pulled...
I got her running. Sounds MEAN. I like it. I know i need to get a factory service manual, until i do, anybody got a step by step on how to change the waterpump? Assuming it is similar to an omc,...
Hi, i have been an omc man all my life, but could not resist buying today a clean original 1981 hydrostream viper, bruiser (blue and black metalflake) with a clean old freshwater 1973 115 inline...
Start with a pad the width of a padded boat of similar length and weight. If you boat 200 pounds heavier, then add an inch to the pad. One note, make your pad entirely of fiberglass that way if you...
was curious what the actual propshaft dyno numbers were on the old early 1970s 115 inlines, and the 135s, and then the later 150, and finally 140? also, what about the last 115 inlines? i know the...
I got a 56 ci looper that i bought with the understanding it dies when put in gear. Compression is decent and even. I popped the carbs off today to drop in the soaker adn will rebuild them,...
Assuming they weighed the motors fully dressed, anybody else notice how much lighter the Chrysler 49ci is than its competition in its day, same thing with the 135-150 stacker?
They are like 50...
I know, I know, they ain't fast, but it was my dads he got brand new back in 1965 so i want it. Still keeping my padded V Hydrostreams and Allison 13r, but curious what hull mods have been made to...
one of those 65 motors, at least one year, 72 or 73, i think, had an awesome lightweight flywheel that can be used on the later 75 stinger.
i imagine its a heavy boat, a 13 x 15 might be all you can do. get a tach and if only spinning around 5k, i think you need to step down further. if she is really turning up, try a 13 x 17, but my...
buzzer comes on and stays, even when cold. purple b + wire has no current.
any ideas whats wrong?
oil tank looks full, cap tight, fuel is fresh.
thanks
I know on the larger etecs (150 in particular) they have a lot of power, a whole lot, but again, if putting the 150 on say, a 700 pound 18 foot padded v, that already isn't handling the best due to a...
i think stoker (the pubahh on evilrudes) said to watch out on those fichts till, i think, late 1999 when brp took over. stear clear if 700-800 hours on motor. the ecu is a lot of money on these...
On the later 56 inch motors, what are the differences? I can get a good clean 1996 60 for cheap, but i also have a 1987 70. Someone mentioned that the tuner is better for top end on the 60. If so,...
are they hard to find for this motor? i thinik it needs one or the other. thanks how much?
Got access to a 1987, i think, 125 force. Is this any good? How does it compare to 140 crossflow, or an old inline 6 merc performance wise?
Thanks
But i have talked to a lot of experts (well, a couple). This is some basic info, get the specifics from a stoker or a nerstrom;
1) 7 inch tuner
2) 1973 135 heads (but you have to run some...
15 inch motors were geared higher and bullet is about 3/4 narrower i think
thats an oldie there, Randy.
this was before he let his hair grow out. this must be one of the very early race pictures.

You know, roger told me about a jeannie bowen that knew a lot about the boat, am assuming this is her. I remember now, a "jeannie" being talked about now. I think i remember seeing her years, and...
Hey, randy, did you ever talk to jerry. Remember we talked last year and i gave you jerrys phone number. I send roger hinsdale the o'berry hat and shirt and he did an awesome job making copies. I...
Ron Baker told me that with the Chrysler, he could jack it to the moon and it ddnt lose water pressure. He said the motor wasn't all that great as far as being a screamer, but it was purely the fact...
My 13 Allison (1972) is being restored as I get time, transom, core, the whole shabang. I have a question;
I have an old (1980 ish) 75 OMC, not a nitro-cased motor and it has always been...
I don't understand many things, but help me understand how cars like the 1970 buick gs 455 stage 1, with 455 cubic inches, and only like 375 horsepower (also only had a hydraulic cam) could pull that...
Anybody know if the coastguard will let a boat like this operate as a pleasure machine today?
About how fast with a stock 140 crossflow and a 200 pound driver? And what prop?
Thanks
Anyone know anything about these? I heard a guy named Jim Bergendall was involved with them out of Illinois.
Good boats or not? A lot of them left?
Thanks
I am sure there is something i am missing here. I hear a lot of guys are into the 90 yamaha 3-cylinder motors, but unless i am wrong, I don't get it, because doesn't it weigh almost as much as a 140...
Anyone make an aerosol of the orange used on the old stinger gp? If not, what did you do gohr? Did you use a preval and hugger orange?
Thanks
Bang for the buck, would a stock 70 hp fishing motor (56 inch) whip a 75 nitro case stinger out of shear grunt? I know the lower is not as good, but it sounds like it would win.
Okay, i have an old 75hp (non-nitro case) and was told that the newer 56 c.i. Has a lot more "spank" to it down low, in the middle, and on top. Is this true?
If so, could someone tell me the...
A Friend Just Picked One Up And I Noticed It Has The Tiniest Bullet On It. Anybody Ever Run One Of These On A Fast Hull?
Are They Decent? I Hear They Burn Dirty Due To Old Technology (namely...
anybody got any pics of some of the 1970's gold/green v-4 that look good?
thanks
the pics above are awesome. where did you get the louvered cowls?
that's a huge difference in top end. you know the weight difference between the 75omc and 85 inline?
does the 85 have a lot more punch throughout the powerband?
anybody have any good pics of the coolest looking factory (factory race or fishing motor) of the old motors (evinrude or johnson). am painting mine and want it to look very factory and very 1970's,...
what are the gps numbers, and what were they with a 75 omc?
am curious as i have both motors to try.
Was Curious About This 850, Too. How Fast Does It Run On Your 'stream? What Model Stream (vixen, Vandal, Viper...)?
Have You Compared It To A 75 Omc?
Roger,
I Talked To Bill Oberry (phillips Brother) Last Night And He Does Not Have Any Pictures Or Anything Else On This. I Stopped By One Of The Other "old Guys" Houses Last Week And He Was Not...
A buddy of mine is selling his 85 inline, long shaft, no trim, and i am curious about the motor. are they decent motors? good power, weight?
how does it compare with the old 75 omc loopers? i...
Anyone Know The Weight Of These? Wheres The Best Deal On A Wiring Harness On This? Thanks
it was a 76 115, nothing special, $200 motor. flatback, totally stock.
is it worth adding the 135 carbs? friend of mine told me that is an easy 3-5 hp. any truth to that? where do you get...
anyone have numbers on the inlines (6 cyl in particular)? curious also the difference on lighter hulls you have seen from a 115 to a 135, 140, and 150?
i ask because i have a 115 (1971 i guess)...
i got 67 mph on a gps with an old flatback 115 crossflow. should i see similar top end with the 1971 115 inline or not?
also, two "old school" mechanics told me something that was a little...
what did they run the 50 hp on in those days, performance wise? 11 foot padded v bottoms or hydros or what? i heard they are super thrifty on gas.
