My new to me Allison is getting a bit more oomph on the back. Recently purchased a less than 50 hour 2001 vintage mercury factory built 2.5 long block with some goodies bolted on it. VST is deleted, has lightweight flywheel and 16 amp charging setup, Boyesen reeds, Geneva Fla. local David Dreifort's throttle linkage, choice of 225 or 260 tuners, 2 piece adaptor, 39psi fuel regulator, leaving the limiter set stock. A Simon alternator kit is on it, the slight power suck bumps the charging up to 65 amps or so. The Geneva locals are a small group of boaters known for their 120 mph outboard rides...
The old, Titus coned '88 vintage 150 preload gearcase that my Promax 150 powerhead/225 Promax mid came to me with has a history of abuse and lots of hours, and likely is not ready for the increase in power. Since the skeg has been welded twice on it, is likely unsafe at higher speeds anyway. Might be OK in the future for a 35-40 mph Bayliner Bob type of boat with a fully submerged prop. I'd sell it dirt cheap. Am getting a compression check done on the 150 BB block factory powerhead before yanking it, it will be up for sale, nice runner with a history of richly ratio'ed premix run through it since nearly new.
Found a used Sportmaster 1.87 fat shaft with an "Allison" cut skeg from a Geneva based seller with some fresh guts inside that had a 20 inch driveshaft replacing the 15 installed right before shipping by Geneva local gearcase legend Jason Wolf.
The Hydromotive 4 blade prop custom made for the boat had a fatshaft hub put in it today, but the Quicksilver 26 pitch Trophy regular shaft wheel was an older design that does not use the flo-torque hub so it now is up for sale. It looks like solid 8 1/2- maybe 9 condition. Time for prop shopping becauseI need a spare.
The boat has 80-85 pounds of downriggers and balls carried in the gunwales slightly forward of the midsection when they are mounted and the Ultrex is heavy enough that I needed to remove the ballast out of the port side rod locker. The 150 is on a 14 inch setback fixed jackplate, propshaft center even with the pad. It pushed the XTB at 6200 ft above sea level with just me and a couple fishing rods in it to 62 mph and 5800 rpm with the 26 hydro prop bolted to the the old 2/1 case. Guessing with the 225 powerhead and 1.87 sporty that the hydro might just hit or be a tad under the stock limiter at 6750 rpm WFO. What ever prop I get will be for going fast lightly loaded without the downriggers, since I already have a 4 blade that should be fine for with them. Maybe a Hoss, Mazco, or chopper, am open to suggestions. Needs a fair amount of bow lift. Hole shot is less important than high speed.
When I took the boat in to be rigged for multi species fishing it snowed a fair amount here In Utah, just like when you take your car to the car wash it rains...When I dropped off the boat today for the repower, the NOAA infared satellite showed a series of storms is approaching from the west, and starting tomorrow afternoon it is supposed to snow off and on for the next six days, a couple feet might fall at Park City Mountain Resort where I teach private ski lessons to the darlings of Hollywood and Wall street. The lake won't be frozen by a week from now on my next day off to pick the boat up but there might be some snow down to the water's edge, will bring a 25 lb. spud bar and sharpened spade shovel to clear ice off the boat ramp in a path wide enough for the wheels of my 4wd truck to be able to pull the boat back out... Gonna wear a full on snowmobile suit under the clipped in life vest, and of course...The trademark Elmer Fudd hat. More cowbell...!!!
