Does anyone have any experience in re-powering a 1999 Horizon 170 outboard? The Johnson 115 2-stroke is rated 318 lbs. and all the possible 2-stroke replacements seem to be around 400 lbs. I'm just looking for advice from anyone who may have already dealt with this issue. What would be the optimum choice to replace this engine with a new engine? Motor is 1999 Johnson 115 HP J115PLEE 20" shaft Replacement option 115-HP E-TEC SPECIFICATIONS Models a. E115DPL b. E115DSL c. E115DBX d. E115DPX e. E115DCX Shaft Length mm (in) / Color a. 508 (20") Blue b. 508 (20") White c. 635 (25") Blue d. / e. 635 (25") White Weight kg (lbs) a. / b. 170 (375) c. / d. / e. 177 (390) Engine Type Loop Charged V4 60° E-TEC Direct Injection Bore x Stroke mm (in) 91 x 66 (3.601 x 2.588) Displacement cc (cu in) 1727 (105.4) Ignition System IDI Fast Rise Inductive Ignition Starter Electric Trim Method FasTrak Power Trim and Tilt Propshaft kilowatts (HP)* 86 kw (115 HP) @ 5750 RPM Full Throttle Operating Range 5500-6000 RPM Digital Throttle & Shift - Gear Ratio a. / b. 2.0:1 c. / d. / e. 2.25:1 Fuel Induction E-TEC Direct Fuel Injection with stratified low RPM combustion mode Alternator Variable Voltage Computer Controlled 133 Amp** / 1800 watt output with Regulator Cooling Pressure and Temperature Controlled Water Cooled Steering Remote or Accessory Tiller Also, I found this calculation for max horsepower? Is it valid? stern width * length * 2 -90 = horsepower 7 * 17 * 2 - 90 = 148 Another question... what would be the impact of going to a 25" shaft? |

I'm not real sure about the 170 H, but my 180 H is rated for up to 150 hp. I would think that would open up some options for you. |
