boatall blocking must be strong enough are available locating tbe sbaftto support this weight plus that of bole and establishing the angle isthe people working in the boat simple It is only necessary to lay down a fullsized profile in someAs the first step shore up the boat convenient spot and place over thisuntil tbe bull is approximately drawing fullsize cutouts of thethree feet off tbe floor

blocking sbould be used and 4 wide for a threeblade propalong tbe keel and 6 wide for a twoblade Tbe engine cutout should be a fairlyTbe next step in tbe procedure is accurate reproduction of the tbe

througb tbe keel carefully noted The position of tbe engine is then carefully cbecked to be sure there is suffi cient clearane between it and tbe bottom of tbe boat and tbat tbe angle of tbe engine does not exceed tbe Figl Location recommended operating angle 5 to of Underwater Gear 14 degrees in most engines The 4 A justed to obtain proper propeller clearances and crankcase and fly wheel clearance for the engine When the position of the string has been accurately determined the place it passes each of the sticks is care fully marked and the jig placed back in the boat It is then a simple matter to lay a straightedge along c these marks 123 on Fig2 to the I bottom of the boat which will give the position and angle of the shaft hole prNOFNtIGN 6Wr 2 INSTALLING THE PROPELLER SHAFT A wedge is now constructed whichFig2 Method of Locating Sbaft Hole will fit between the keel and the inboard shaft log This wedge mayengine must be lined up eitber by be fashioned from any hardwood butraising or lowering it or changing mabogany is recommended since it isthe angle Do not move the from its locationIf full scale drawings of the boatare not available another simplemethod of locating this spot is tolay a length of 1 x 4 lumber fromthe center of the transom forward to aspot well beyond the determined engine 10cationSee Fig2 Temporar i ly prop this str ip A in place soit is roughly

can now be removedand laid flat on the floor In this event the underside of the wedge should be shaped to fit theA string is then stretched from the keel and tbeedges shaped to fitboard which represents the transom alongside the keel and fit the hullto the one represent ing the locat ion as snugly as possible The wedgeof the fl1heel The string is ad should also be notched out to fit 5any ribs which might interfere The A drill 18 inch larger than thewedge is then screwed into position shaft diameter should be used toover the locat ion of the shaft hole provide PI opel clearance Any typeUse a good grade bedding compound of drill may be used which willbetween the wedge and the keel and drill a clean hole and has a shankfasten securely to the keel with long enough to pass through the twoscrews being careful to place these blocks and the keel A standard carscreTs where they will not interfere penters auger is not the shaft log mounting screws since the wore tends to follow the

the keel and the bottom block it can be re IEL moved and the two temporary drilling blocks unscrewed from the boat Now lay the shaft log on the wedge and over the shaft hole In some cases it will be necessary to chiselFig4 Method of Drilling Shaft Hole out the wedge to conform to the bot tom of the shaft log Make thisAfter the wedge is in place pre notch slight ly larger than necessarypare for the drilling of the shaft to allow for later Preparation for this step a gasket from 116 rubber or 132consists of the construction of two gasket mat er ial and place it blocks which will act as the shaft log and wedgeguides in getting the shaft holestarted properly and keeping theangle of drilling fairly accurateThese blocks should be of hardwood maple or oakwi 11 do They should be
