Mark,
I am only selling one of the 67 Sportsman 155's. I use the one for
fishing. Just deciding which one to let go. One has rebuilt motor and
new seats, other one is all original including seats. I just need to
reinstall tilt motor as original was acting up. Once I get one ready to
sell I will post pics.

Hi Rob - What are you going to ask for your 67's. Could you email me
some pictures. Thanks Mark (mrnick37@...)

Hello
I also live in Michigan and have been watching the Rogue. I would like
to see this one back on water. Should the price not go too high I will
try to aquire it for restoration. I doubt it will take much to get it
running. I have two 67 sportsmans and will be selling one soon. I also
have a restored 64 Johnson deluxe with V6. I have been considering a
larger boat like the 19 footers with V8.
Do you need a upper gearcase or just looking to keep one for a spare?
Regards
Robert

Hi Lee and list members:
Thanks for reply. I'm thinking about bidding on a cheap '67 rogue on
ebay right now, mainly because it has great seats identical to the '68
sportsman seats, and because it's only 50 miles from my Sportsmans in
Michigan. But the cost has reached $360, so it would be great if it had
significant other parts I could use - like the outdrive. Hence my
question on whether it is practical to switch gears in the upper
gearcase. I figure if I wear out a Sportsman outdrive, hopefully its
upper gears can be transplanted into the outdrive from the Rogue.
Anyone wanting a '67 Rogue in good condition should take a look. This
one has a lot of life in it and should not be a parts boat. Says the
engine does not start, but also says it has sat for 10 years unused.
I'd withdraw if someone on the list wanted it to restore:

Hi Doug,
So let's be clear about your goals? Your asking if it's possible to
take the outdrive assembly from a V8 and replace it's UPPER GEAR SETS
(21:16; 21:17, 21:18, 21:19) with UPPER gear sets from the Buick V6
(25:25) ratio's ? I'm unclear because your footer lists 68 and 69
Sportsman's which probably already have V6 (25:25) stock gear sets?
First make sure you have what you think you have: Is your V8 unit a four
or five bolt cap unit? You want the later five-bolt cap units introduced
after 1967. Secondly is it a long-shaft or short shaft?
Short shaft's usually came off later Ford V8's (170-190-235hp) which
had different ratios (see my chart). You notice they all share common
lower gear sets of 15:23. It is the upper gear sets that vary.
I've never personally done this job, I understand it can be complicated
by year-to-year changes and differences in shims, bearings, etc. Mixing
and matching usually leads to problems.
What I did was to exchange the entire power unit without cracking open
the units. At my altitude, I considered the fact that my 21:16 V8
gearing is a little tall, but I have enough room to still compensate by
running a relatively short 13-inch SST prop. The 21:19 set used in the
165-hp, straight six Chevy is ideal but hard to find. The 302 Fords came
in 175-hp @... 21:18, and 190-hp @... 21:17 but were usually as I said before
short-legs. Remember I have a 24 per cent power loss when I run at 7000
feet, so I seriously considered running lower V6 gearing in my V8. The
benefit of running the taller V8 gearing is I get fantastic cruising
fuel economy, (that is provided I'm not into the secondaries of the
QuadraJet.)
So to summarize: Find out exactly what you have, by counting teeth, or
precisely counting input to output rotational relationships. And either
exchange entire down-leg units or find someone mechanically familiar
with rebuilding the outdrive with the desired gear set ratios.
Happy Easter
Lee Shuster

Subject: [OMC-Boats] Outdrive Gear Ratios v6 versus v8
Hi Lee and list folks:
Lee, when you upgraded from the V-6 to the V-8, did you change the gears
in your outdrive? Per your prop page, these engines used different
ratios in the upper gears:
http://hhscott.com/evinrude/props.htm
I'm wondering how to do the reverse - to change the V8 gears in an
outdrive to gears designed for the V6. Is it a simple matter to switch
these things out?
Thanks for any info.
-Doug Julien, '68 and '69 Sportsman 155's
