not sure we are done hear, i think thare is more to be learned, is 550 to many?
do you know what Merc rods to use?;):cool:

stock Mod50 jets, 19S- 45's lowspeed 40's highspeed:eek:

Merc, merc piston on the left. a short 3.400, what else you got on them Merc long rods?:cool:

loose the stacks, with the 31m or straight in front 1/2, thinkin that 25hr life span becomes vary real cuzz of the castin liner.

put a crank in them cases and torque them to spec, check the spin...

is that a one to one, i'm not seein the linkage set up:eek:

them rods

the Bullet on the right is out of stock Stinger, the one on the left is about .400 thou bigger, which makes it about .200 thou bigger than a .040 over 56er piston,:cool: note the same...

thare should be a shot of them rods on hear, around page 10 or 15,?, not sure .

to run a longer rod within the deck height of a shorter rod, the wrist pin location gots to be moved up.

more...

big twin 40hp rods or Mod50 rods.

two ways to fit a piston, one is, custom hand fitted, the other is production style, nether is wrong, has to do with what your buildin.:eek::cool:

"the straight in", had bigger reed blocks, the front half went straight in ( the down sweep was removed), had press in cyls with a single vert exhaust bridge.
made about 10more hp than the 19s. she...

i'm likin .008, i'd see what Dave at Sea Way had to say, then go from thare.:eek::cool:

NO, this statement is wrong and or not true.
this is true, the forged piston Diameter + .008 = the Bore. which would BE a tight fit for said bullet.

the more bore that is removed from the...

at.040 over bore, it is common to give the forged piston up to .009 thousands total, thats the piston diameter plus .009 total.

so when the piston is in the hole, centered, thares a .0045...

wisecos expand, unlike a cast piston the wiseco IS guna grow .004 when it heats up. if you set a forged piston at cast piston specs it WILL stick.

:cool: gots some jet specs some ware:eek::cool:

.008 for a wiseco, thats the the piston die' plus .008 thousands.
on a stocker i'll lean a bit on the loose side of the spec, just a bit.

but mostly usein wisecos my self. In independent testin...

the oval port is newer, the oval exhaust port make of a more rounded power band. the split exhaust is the one, cuzz of the bridge it can be made bigger over all, you can incorporate the oval style in...

ya, only works on one bank of a V6.

the intake is the cool side of the bore, it's easier on the parts to run the cool side.

thinkin with a 1 to 1 lower unit with two or more pinion gears,...

with starboard exhaust the piston rides the exhaust side of the bore on the power stroke for the better seal, it's also the hot side, works it harder. works the same on a V6.

most likely had a...

reg rotation, the cyl gets a better seal on the power stroke, the Moda makes 10-12 more hp than the port side exhaust case.:cool:

the only notes i could find on Mod50 fuel pressure was 3-5psi, 80gph min.

the 80gals per hour is the minimum.:cool:

you are a long way from a 25hr life span with a stocker or a Mod Stinger,
the one ring Mod50 piston, the long rod makes piston speed faster, the BTUs made, ya a long ways.

it cool to see all...

gots me one of them McCoys, gots the part number for the sleeves?

25hrs????????????? , thares a Stinger 65hp at the shop, thay got it New back in the day, got way more than 25hrs on it.:eek::cool:

you got cast in liners or pressed in, in that case your runnin?
nice rig.:cool:

got 4 more for backup, usein grade 8 to hold it on thare:cool: lets see what you got.:eek:

hey J.T. you out thare? hears them shots of the rig i'm runnin as tested.
that set above, fuel injection, ya 3 banger fueler.:eek::cool:

<a href="http://tinypic.com" target="_blank"><img...

seen needles like that on the low speed of a 55hp 3 banger. low speed circuit never stops pullin, so with a needle in the low speed, and the main within range , you should be able to fine tune...

ok, this is the port map:cool:

:cool::eek::cool:

had me some of them Mikuni fed 3cyls 2 strokers. after many tests it is my opinion that the 56er is geometrically challenged, and is not capable of the peak
hp of the 49,i've heard tails of dynoed...

i gots a Mod50 with press in liners, has the 56er exhaust port, she needs new sleeves, think that would be some thing you could do

anywho, at test done at the factory on the 56er, with, without modded exhaust, long rods, 2bbls, it never made more than 102hp no mater what.

in tests done by my number one tester, at 800ft it's...

good stuff, can you tell us more on the coolin system of the 56er.:cool:

testin is key,:cool:

i'll check out that Konig stuff.:cool:

i talked to a Dude that worked at OMC, he built Mod50...

the more meat you take out of the crank case the lower the transfer psi.:cool:

i would want to see how the rotary valve set up worked on the outboard. no clutch, sleds gots a clutch, bike ya it's got one too. was a dude that ran a Rotax, i think, i was not thare, but any way i...

hey 850,
nice finger ports, the blending work looks good as well. that head is nice, who made it? what happened, can't see the cyl' walls good, looks like a hone and reload with fresh rings from...

cool, would like to see it.:cool:

i'm not sure ware BRIAN HENDRICK saw that moda, maybe he will tell us.:cool:

on the bridge, ya you can thin it out, but then it kinda looses it's power to cool it's self, and runs at a hotter temp...

i'll say some stuff about the bridge, right now getin me some food.:cool::eek:

Hay J.T., you out thare, gots that adapter you were lookin for.
seen some biger than 90hp carbs:eek::eek:, i'm not sure thay will stack up on the 90hp intake, cuzz thay are so big they may not fit....

looks like could have gone wider, but lookin good right thare;):cool:

ya be best to see them rules, finger ports? wiseco's? twisted port map:eek:?

open house on sunday, had to pull down my power Mantle, but i took a shot first. i pulled this one outa the woods, tricked it up and mounted it.:cool:

Hey JT you out thare, have a good B-day man, i hear thares a Fast Fred Mod50
out that way with Yamaha 3 ram tilt and trim:eek::cool:
thanks for your help on stuff:cool:
lookin for an adapter for...

they all would be considered Cheater Modas in that class.

gots one i'm buildin, SST60SIXPACK:eek:

not only would you get DQed you would be Band:eek:

stock bore wiscos :cool:

a peak at some other related stuff.:cool:

page 16, thare is a factory 19s head. i'm runnin flat top bullets so the squish band needed is not the same. runnin a tricked stock head, found it on a shelf in like New Jersey or some place over...

hay 850, have a good day:cool:

can't seem to get that to fire up,?

i was tryin, took the time off, it wasn't comin together on a co-pilot. see about workin the co-pilot thing out now, next year think the Deanster will be lookin to run his new hull too at the Top O'....

ok, on the dyno they said some thing about they was pushing the fuel,thinkin the pump they was runnin did not have enough volume to feed it, so they moved the floats on thses carbs, ya i remember...
