II. INTRODUCTION
The Models P200, P300 and P400 hydraulictransmissions have been designed for smoothoperation and dependability in marine use. Thetransmission is self- contained, having an oilpressure system and oil supply completelyseparated from engine lubricating oil systems.
TransJ1lission oil under pressure is used toengage a forward or reverse drive. The for-
III. INSTAllATION
A. The installation instructions below are foruse when the original transmission has beenremoved for servicing and must be reinstalled, or when the transmission unitis to be adapted as non-original equipment to a marine engine.
B. It is important that the engine and transmission rotations are matched. The direction of rotation of an engine is defined inthis manual as the direction of rotationof the engine crankshaft as viewed from theoutput end of the transmission. A clockwise rotation of the engine is a right handrotation and a counterclockwise rotation ofthe engine is a left hand rotation.
A letter "R" or "L" appearing on thetransmission serial number plate illustrated in Section I, "SPECIFICATIONS",indicates whether the transmission is foruse with a right or left hand rotatingengine.
C. The hydraulic transmission is attached tothe engine in the following manner:
1. Insert two 3-1/2" studs in oppositetransmission mounting holes in theengine adapter plate.
2. Place the transmission against the studsso that the studs go through two of thematching holes in the transmissionhousing flange.
3. Slide the transmission along the studstoward the engine so that the spline onthe shaft at the front ofthe transmissionenters the matching splined hole in theengine vibration dampener.

ward drive is through a multiple disc clutcharrangement, while the reverse drive utilizesa reverse clamp band and planetary geartrain. The transmission oil is circulated andcooled through a separate external oil coolercore, which is in turn cooled by the enginewater. Paragon transmissions are furnishedwith either direct drive or reduction gears.Gear reduction ratios and correspondingmodel identification numbers are listed inSection I, under "SPECIFICATIONS".
4. Install and tighten four bolts with lockwashers through the transmissionhousing flange into the engine adapterplate. Remove,the 3-1/2" studs. Installand tighten the two remaintng boltswith lockwashers through the transmission housing flange.
D. The transmission and propeller shaft coupling must .be carefully aligned before thepropeller shaft is connected to the transmission, in order to avoid vibration andconsequent damage to the transmission,engine, and boat hull during operation.To 'align the coupling, move the propellershaft, with attached coupling flange, towardthe transmission so that the faces of thepropeller shaft coupling flange and transmission shaft coupling flange are in contact. The coupling flange faces should be
. in contact throughout their entire cirCumference. The total runout or gap betweenthe faces should not exceed .002" at anypoint. If the runout exceeds .002", reposition the engine and attached transmission'by loosening the engine support bolts andadding or removing shims to raise or lowereither end of the engine. If necessary,move the engine sideways to adjust therunout or to align the coupling flangefaces laterally.' Tighten the engine supportbolts and recheck the alignment of thecoupling before bolting the coupling flangestogether. Connect the coupling flanges withbolts, lockwashers, and nuts.
E. Connect the oil cooler lines to the transmission.
F. Connect the shift control cable from thecockpit control station to the transmissioncontrol valve lever, shown in Figure onpage 5. Place the transmission controlvalve lever in the neutral position and
adjust the sl,aft control cable length untilthe cockpit control station hand lever isin the neutral position. Move the cockJ?itcontrol hand lever to forward and reversepositions several times while observing thetransmission control valve lever motion.The transmission control valve lever shouldmove fully into forward or reverse positionwhen the hand lever is moved into forward
IV. OPERATION
Principle of Operation
The transmission forward and reveI1'- drivesare operated by transmission oil unddr pressure. An internal gear type oil pump deliversthe transmission oil, under pressure, to theexternal oil cooler. The .transmission oil isreturned, still under pressure, to the oildistribution tube and relief valve. The reliefvalve maintains the oil pressure by remainingclosed until the oil pressure reaches 60 PSI.When the control lever is shifted to theforward position, oil under pressure is delivered to the multiple disc clutch piston,which moves to clamp the clutch discs andplanetary reverse gear case together. Thediscs and case then revolve as a solid coupling in the direction of engine rotation. Thereverse drive is engaged by shifting thecontrol lever to the reverse position, so thatoil under pressure is delivered to the reversepiston. The reverse piston moves to clampthe reverse band around the planetary gearcase, preventing the planetary gear casefrom moving but allowing the planetary gearsto revolve to drive the putput or propellershaft in a direction opposite to the rotationof the engine. With the control lev~r in theneutral position, pressurized oil is preventedfrom entering the clutch piston 01' reverseband piston and the propeller shaft remainsstationary .

or reverse position, and should returnexactly to the neutral position when thehand lever is in the neutral position.
G. Remove the oil dipstick, shown in Figureon page 5, and fill the transmission withType A transmission fluid to the mark onthe dipstick. Replace the dipstick in thetransmission housing.
Starting Procedure
1. Always start the engine with the transmission in NEUTRAL to avoid moving theboat suddenly forward or back.
2. When the engine is first started, allow itto idle for a few moments. Stop the engineand check the transmission oil level. Addoil if necessary to bring the oil level upto the mark on the transmission dipstick.
NOTE
ON SUBSEQUENT START-UPS, THETRANSMISSIONOIL LEVEL MAYBECHECKED BEFORE RUNNING THEENGINE, WHEN ENGINE OIL ISCHECKED.
3. Start the engine again, with the transmissionin NEUTRAL, and,allow the enginetowarmup to operating temperature.
4. Shift the transmission into FORWARDorREVERSE as desired. If the engine shouldstall when the transmission is shifted toFORWARDor REVERSE, place the transmission in NEUTRAL before restarting theengine.It is recommended that shifting be done atspeeds below 1000 RPM, and preferably inthe 800 RPM, or idle engine range, to prolong the life of the engine, transmission,and boat. EMERGENCY shifts may be athigher engine speeds, but this is not arecommended practice. •
V. MAINTENANCE
A. Lubrication
The Models P200, P300 and P400 transmissions are self-contained units, independent of the engine lubricating systems.The units are lubricated by pressure and bysplash from its own oil. The type of oilrecommended is "Transmission Fluid,Type A", commonly used for automatictransmissions in automobiles.
The quantity of oil depends upon the angleof installation, as well as the reductionmodel. The level must be maintained atthe mark on the dipstick and should bechecked periodically to ensure satisfactory operation.
When filling for the first time or refillingafter an oil change. check the level afterrunning for a few minutes to make certainthat the oil cooler and the various passages

are full. If necessary. refill to the markon the dipstick to ensure proper operationof the transmission. The transmission oillevel should be checked each time the engineoil level is checked, before running theengine.
The oil in the transmission should bechanged every 100 hours, or each seasonunder normal conditions. However, thenumber of hours that can be run betweenoil changes varies with the operating conditions. Drain plugs are located at thebottom of the reverse gear housing and thereduction gear housing.
B. Adjustments
No adjustment is necessary for the FORWARD drive multiple disc clutches, and thereverse band is self adjusting to compensate for lining wear, so that no externalreverse band adjustment is necessary.
