SST-120 Outboard Racing

     SST 120 is a premier racing class world wide. We have been working on this engine ever since it was introduced in 1989. My brother Jerry won the first title event at the Kankakee Nationals for the (then new) SST 120 engine. I worked for 5 years at Mercury Racing were I did all the work on the new (current) piston design. I know this engine well as a builder, and I know it well from a detailed manufacturing stand point. I know what the factory did and why. I have assisted in training the Tech inspectors in APBA, and in UIM. I know how far you can push, and where the line is, so you do not cross it. No where else can you get this experience.

     There are some very key areas in the SST 120 engine. We can actually measure your parts in a special layout we have developed. This is an evaluation of all ports of each cylinder, stroke of each cylinders, Connecting rod diameters and lengths. Pistons clearances with bore sizes.

     I can tell you if you have possible winning equipment just by doing this layout. It is possible we would recommend some different components. Some of these parts have very large manufacturing tolerances. To have a winning engine in this very competitive class , these details have to be in a much narrower range. There is a certain set of good numbers you must have to win. Some parts are correctable with in the rules. Some are not.

     WPT have developed an ignition testing machine. We can now test a complete ignition system up to 9200 rpms. We can monitor each cylinder with a digital oscilloscope to identify problems and or bad parts. Part by part can be evaluated. This can certainly save you a bad race and more important, it can save a major engine failure caused by ignition failures.

     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.
