    1975 Evinrude 70 HP Poor Power and Acceleration-Which Direction Do I Go?

    1975 70 HP Evinrude on a 20 Ft Poontoon, I just got this motor and isntalledit on the boat last week, finished hook up of cables and such today. Motor will start and idle fairly well. Before hanging the motor I replaced the water pump, and put new plugs in it. Today I backed it in on the...

    Engine Swap-Stuck on Control Cables

    OK, Replacing a 1989 40 horse Johnson VRO with a 1975 Evinrude 70 horse. Pontoon has a binnacle controller. The engine end of the existing shift and throttle cable seem to be 2" too long on each, there is not enough adjustment with the black nut/adjuster. Would this swap require me to get...

    Engine swap questions

    Repowering our pontoon, took off an 89 Johnson 40 HP, found a good running 75 evinrude 70 HP. Boat has a binnacle controller. Will the big red plug match up? Any issues I'm not considering, it seems a pretty straight forward swap.

    Binnacle Adjustment

    1989 Lowe Pontoon and 40 HP Johnson, boat has original top mount binnacle. The shifter moves fine, functions fine, but the stop or detent for neutral is very slight, it can be hard at times to get it just right so the starter will engage. Can these be adjusted and lubriated?

    '89 40 Horse Low Compression but Starts and Runs Okay, What to look at

    1989 VRO 40 Horse, VRO has been removed and runs straight 50:1. This engine is on a 20' pontoon I bought a year ago from a small dealer/salvage. Starts easy and idles/runs good, but it seems to have less power than expected. We run a 12.5x13 prop and only get 11-12 mph GPS @ 4500 RPM. I...

    Prop confusion!

    I have a 20' Lowe pontoon (2 logs) with an 89 40 hp Johnson on it. Motor runs well but is getting kinda tired, I want to repower it with a 70 hp looper but till the right one comes along we will putt along with the 40 horse. A week ago we spun the old prop that was on it, it was a 3 blade...

    Bad grounds cause this?

    I f the stereo in the boat causes the temp gauge to beat to the music, louder you turn it up the more pronounced it is. Also if you turn the stereo off the gauge drops 15 degrees, would bad grounds cause this?

    470 Cooling, Would this work?

    Ok, '81 470, 3" exchanger, I've worked over all areas of the cooling system and still verging on over heat if I run WOT for very long. I have my eyes open for a 4" heat exchanger cheap, which is not very likely. But I had the thought, if I find a 3" exchanger why couldn't it be hooked up "in...

    I shouldn't worry, should I?

    1981 470, been running great, cooling great, just did alt conversion, all is well. Couple of evenings back I was out flinging teenagers off the tube, running pretty hard. Temp gauge (new this year, probe is in the exhaust manifold) never showed above 180-185. The old boat has idiot lights in the...

    Ok '81 vintage 470, all stock including charging system (not yet converted) We've run the boat a half dozen outings since we bought it in Feb, I do get an indication of 16-17 volts part of the timeI've verified it with a multi meter and the fish locator has a built in volt gauge, it usually will...

    Trim Tab Adjustment

    470 with MC1 So is it normal that there is no "sweet spot" on the trim tab adj that works through out the rpm range? I've gotten the boat to track hands free @75% throttle, or @ WOT but no matter how I try it pulls one way or the other at most rpm settings. Will a 4 blade prop make any...

    470 Alternator Conversion, Couple of Questions

    So, all the posts and discussions of catastrophic failure of the 470 charging system have me proactively replacing mine with an alternator. I have a 1 wire marine Deloc type alternator a buddy gave me, and I'm going to fashion brackets for it, here are my questions: 1. I see the breezeworks...

    Lost on prop selection

    18' v hull glastron, 470 MC1 combo, 170 HP. Ran her out this weekend 2 people and 3/4-1/2 tank of fuel, after playing with trim had 47 mph indicated (speedo not GPS but I'm stick to it!) @ WOT & 4900 RPM. RPM is too high, I'm looking to get it into 4200-4300 range. I'm assuming I could run...

    470...Another Weekend, Another Question-Closed Cooling System

    1981 470 MC1, Took the ol girl out today, ran flawless, never passed 175 temp. When we came off the water, bilge had maybe 1/4 cup of water when I pulled the plug. Once I had her home I checked the engine compartment to see if anything was happening back there, oil leaks etc. I checked the...

    470 MC 1 Shift/Throttle Adjustment

    Preparing for the weekend, still have one issue that needs tweeked. In water, in neutral we are idling smooth 600, reverse catches and is reasonable just into gear and maybe 700-800. But forward we are picking up some throttle by the time the shift is complete, probably 1000 or slightly high, so...
