Pro Outboard

     Pro outboard racing is a favorite of mine as I consider this my roots in powerboat racing.. I started out with alky Merc deflectors and then Quincy flat heads before moving to Konigs. As an interesting bit of history, I worked for O.F Christner in 1977-78 before returning to Wisconsin and opening my own shop.  I have build winning Konig’s for almost every class and have built many engines from billet. The many years building championship winning snowmobile engines and exhaust systems along with years working for OEMs as lead project designer of multiple engine projects has given me the deep design experience that is so needed in Pro today.

     The modern engines such as VRP and Rossi are nice but, the attrition rate is unacceptable in my opinion. In reviewing these engines in detail, this problem can be corrected.
Fixing the ports and head along with new pipe can increase durability and widen the power band along with increasing the power as well.

     WIENANDT Performance Technology can put the science back into the racing engine.
We are preparing a new computerized dyno just for the Pro outboards.  This will be able to confirm all the computer models work. With today’s advanced computer simulation technology, the dyno only validates our work. The days of cut and try are over. The science of engines can be yours!

     We highly recommend using AIM Data acquisition systems that we have specially developed for Pro racing. These systems can measure and graph: rpm, speed, throttle position, pipe position, head temp, water temp, plug temp, crankcase pressure, fuel pressure, water pressure EGT and more. WPT can teach you how to read your engine data and what it means. Now days, we look at the computer first, and then the spark plugs.

     Bench Evaluation: Disassemble, evaluate all measurements and document only. No charge with Race Prep. Reassemble after cleaning parts if further work is not done by WPT. If/When we prepare your race engine, the above is not charged. It is part of doing it right. We need to know what you need first.

     Dynamometer Break-In Service: Highly recommended. Our test facility can do the break-in of your engine better and in more controlled conditions than can be done on a boat. This saves you time as your engine is delivered to you with knowledge that it runs correctly and is race ready.

     Dynamometer Service: Racers may come to our facility or ship engines to WPT for Dyno tuning and evaluation of many engines in a days time. See which of your engines is better and tune the best performance out of each one. Fuels, Jetting, Timing and even Spark Plugs, are things you can now verify with solid data, no longer just opinion.

     Providing Us With Equipment: You need to provide good parts to work from and WPT can prepare Quality, Legal Race Engine using techniques acquired from 25 years of preparing race engines. Each engine is prepared to the best of the ability of the parts provided. New parts will be recommended when required. It is our goal to make every engine, a winning engine.
