Merc Inline - Boysen Reeds - BEWARE!
 

Auto shop owner had his brother in law blow up a mid 70's 1500 on a 2002
bass boat. They tore it down and rebuilt it "for performance" using Wisco
pistons and Boyson reeds.

Then it came to me to find the "problem".

The Wisco pistons were OK - same as stock except that you need to warm them
up real good before hammering them (being forged).

However after a day of extensive testing we all discovered that the Boysen
reeds shaved at least 500 rpm off the top end, killed the hole-shot, did not
idle as well, and in general hurt the performance of the motor in all areas.

We finally pulled a set of reed blocks off an old crank I had laying around
and slapped them in without pulling the pistons all the way out.

On the next water test the critter "woke up" and acted like the raped ape
the merc 1500 was renowned for. The problem was the new reeds / just the
reeds - no other changes.

I will be contacting Pro-Marine tomorrow and IMPLORING them to pull the
Boysen reeds for the old "direct charge" inlines from the catalog ASAP, the
auto-shop owner will contact Boyson and try to deal with them on his end.

This product is "beyond bad" - they were awefull.

Disclaimer: this speaks only to the reeds fo rthe "direct charge" inlines -
it does NOT speak to any other Boysen reed product - many of which are very
good.

I'm surprised. All my experiences with their reeds have been good. Did you
have metal reeds with reed stops before the change? If so, with the boyeson
reeds were the reed stops used?

A little more info please... I never really imagined much of an increase
for the inlines, though, using the Boyesen reeds.

What reeds did they install? Material?

Single Stage or two stage?

Rob

There is only one Boyson set available for the older inlines with the reed
blocks that wrap around the crank in my catalog. They are single stage as
they use the existing reed-stops.

I don't know what they are made of (yet), they do look too thick though.
What I'm sure of, is that they sucked beyond my wildest dreams.

That's the problem it seems. The Boysens for the inlines use the stock
metal stops, they seem to be an afterthought to add to the catalog. They are
not the normal 2 stage Boysens that seem to be popular and effective. They
were horrific in practice.
