there is a company who actually make these today, I will try and find it for you, it looks like a little anchor type thing and gives impression of a roostertail.
A harbour freight drill press is 100% better than no drill press.
with your boat and motor you will get to speed you desire and then some, I think its brilliant that your doing so well with it....
Blacksmiths were and are very clever people who did and do wonderful work. and I salute the blacksmith's of the world.

no your not getting the point
he has no right to tell me I am rude, I was not being rude,
he could of just said its a possible speed with that boat and motor ( oh no its not) but to tell me I...
and who do you think you are to tell me what I write is rude an unnecessary ?
I only told the truth,
I am not going to believe the bull****, you go ahead and believe it if you want.
Two person load 57kn. Slight backwind = 65.9 mph

if a brand new motor was offered at a very low price it could of been expected, but the omc motors were NOT cheap and it was dreadful to send the motors out like this.
I mean seriously how long...
That all looks very very nice,
But how on earth are you supposed to remember all the technical stuff when testing a motor ? I got last after the 1st sentence.
very cool looking rig up.
I have often wondered about 2 stage reeds, to my mind it must restrict certain amount of flow at stage 1 ?
but not ever having 2 stage I dont realy understand them.
I will stick to single
Nice little motor.
They look great when polished up.
I Have often seen on many outboard forums about how bad the Lost Foam casting process is v the other types including
Sand-Casting , Die-Casting and Perma Mold.
Far too many myths going around...
Somehow or another I ended up seeing this today about new type of spark plugs.
After reading for about 20 seconds on the page I was wondering if this is some sort of joke sent to me.
But it turns...
if people go to the trouble of making spacers, then it must be the way to go.
got to be worth a try with the gaskets.
How did you remove the limiter ? if it was a wire simply disconnected , could you have accidently put it back on ?
I am thinking of simple reasons why you lost the extra rpm .
Was the reeds a nice...
there is no pictures coming up !!!
sounds like something wrong here.
first off the gear ratio is 1.64 to1 so 18 pitch at 6100 so yeah that is possible with a nice slip percentage of around 3.5%. great speed.
57mph at 5700rpm is...
ok been down and measured the deck height of my spare block, got some pretty surprising results, so checked it 3 times with 5 different sets of callipers.
the cheap and expensive make analogue...
I will re- measure again tomorrow, as I have written down in a couple of places the deck height cannot be right
so will re-measure that again tomorrow with 2 different sets of callipers to make...
YES THERE IS
Mercury props go bigger than 15 but not sure if they will fit your hub.
do you know the model number of your engine, or what the size of the hub is ? across the back of the prop ....
Glad you got it done.:cool:
Making one out of stainless is perfect, need to make a few and advertise them, you can bet this has happened to loads of people, especially if a bit
heavy handed on...
It is not just the internals that get left with nasty looking marks, the outside is not a work of art by a long way.
The later cylinder heads also have these stupid " lines" on the outside, it fools...
got to be plenty of props out there that will fit that motor.
Loads of people race the Yamaha motors.
what size is the hub ?
It is not glue, it is the glue lines.
When they use lost foam to cast the blocks the foam is in layers glued together. Glue spills out when it's pressed and drys.
Then when the alloy is cast it...

you said "I believe I still have the port angle gauges I used when porting this engine while working for the OMC race group years ago"
Does this mean you had a race version of the...
No the port is not that shape, thats only my drawings , dont take too much notice of the shape. I am not an artist by a long way ha ha
here below is a real pic of the Exhaust port.
with this pic...
For anyone interest here below is a diagram of the port heights on the 56 ci Oval port motor from 1993 onwards ( not to scale ) it shows
the oval port heights and SST60 heights.
Also showing some...

Kroon brand is good oil, it is SHELL oil..
Kroon are just the marketing and sales of oils and lubricants in Holland and a good few other countries.
Yeah I see what your saying about the thinner oil of the fully synthetic not realy being a benefit to the older type of 2 strokes.
I dont run the vro as dont like that and I prefer to run normally...
that extras 3/4 inch might get you another 1mph maybe more, worth a try.
when in the rough stuff the rooster ona small boat would be a waste if its a big rooster, and when running in the rough I...
thanks joe. I had never heard of it before.
I have been toying with the idea of going to a fully synthetic oil for my outboards, and with fully synth being a bit thinner would run that at 40 to 1...
XP ?
is that similar to XD ? or is this something else
Every time I think I have found the magic 2 stroke , I hear things about it to make me cringe and put that idea to bed.
even the cheapest 2 stroke oil out there if run at 25 to 1 is not going to...
sounds about right
just go up 1 inch at a time until you find the right place for it to be a good all rounder.
no point in having fast top end if it wont go in the rough water that you use..
top speed is not always...
most people when running suface type props cleavers and what not, seem to run with centre line of the prop up as near as possible to the surface when running.
I know it sounds crazy, what that is...
well the cav plate is far too low to cause a rooster unless you were trimmed out realy crazy.
lets say the prop is 12 inch diameter for example and a 1 inch space above the prop to cav plate.
1/2...

easy if you look at the box and use basic uploader button.
Well today I got a bit of a shock when delving deep into the oval port triple block.

ah you only put a chamfer on the sleeve and not raised the original port height .
I see.
not so sure exactly what you are now saying..
so the clear this up a bit . are you saying
1/ this port height is 1.382 the top of the chamfer to the deck ?
or are you saying
2/ the actual...
yeah ported I know, but your not taking into account it has tiny little 21cc heads ? 7cc less than a sst60 ???
put those on a normal 56 and it would be crazy high straight away, so even with the...
so you have got normal compression now then ?
nothing special about 150 psi on a fresh motor, especially if running loads of oil.
that is just normal compression.
what is the compression on your...
yeah I had one of the 1991/2 model year mercury 60hp, fantastic engine idled great ,good amount of power and surprisingly good on fuel.
u did not know until I got it that the heads could not come...
Lucky you ?
Yeah right , you carry on writing it and one day it might all come true..
Meanwhile .. 62820
its surprising how an engine thats been around for 30 years still gets so much interest and is still about the best bang for its size.
I know mercury have their 60 that can be hotted up, but it...
