Re: 1970 Sakonnet E-TEC 90

The spring [in a transom saver that has been mentioned above] is actually quite strong. [The spring] is difficult to compress by sliding the two sections of the [transom saver] support together. In use [the spring] is partially compressed by lowering the engine with the power tilt.

Re: 1970 Sakonnet E-TEC 90

The Evinrude E-TEC does have a Trailering Bracket. I'm not an engineer, but it seems to me it does a great job of supporting the engine when trailered in the up position, but does little to protect the transom from the forces exerted by the moment arm of the raised engine. Bumps on the road when the...

Re: 1970 Sakonnet E-TEC 90

Your thoughts on the transom saver make sense. My transom saver incorporates a strong spring. The power tilt compresses the spring between the two tubes. My understanding is this acts as a shock absorber to cushion road shock and lessen the angular torque exerted on the transom due to the weight of ...

Re: 1970 Sakonnet E-TEC 90

Prop: Evinrude Aluminum 13.2x19 This is just an estimate. The trim gauge has 5 marks, one indicating neutral, one up, two up, one down and two down. I started at two down. Porpoising started somewhere between two down and one down. A small reversal toward two down stopped the proposing. I’d like to ...

Re: 1970 Sakonnet E-TEC 90

I feel two holes up is the correct height. There is an improvement in performance. Time, more rigorous testing and a new prop should yield more definitive results. I haven't experienced any problems with ventilation during tight turns. With the engine mounted two holes up I was able to through bolt ...

Re: 1970 Sakonnet E-TEC 90

Thanks to Jim and Phil for your inputs. I raised the engine to two holes up. I achieved 42 MPH at 5350 RMM (12.7% slip). I was able to get to 42 mph by raising the trim. The elevated trim caused the boat to porpoise. Lowering the trim to stop the porpoising. I plan on keeping the engine two holes up...

Re: 1970 Sakonnet E-TEC 90

14a.jpg The anti-ventilation plate is currently 1/2-inch above the extended keel line. Raising the engine one or two holes would result in a distance of 1-1/4-inches or 2-inches above the extended keel line. Two holes up might make through bolting of the lower bolts possible.

1970 Katama to Sakonnet project complete

I’ve finally completed the restoration of my 1970 Katama. I’ve owned it since 1990 and used it until 2001. Circumstances led to a long period of disuse and neglect. She’s come back as a Sakonnet with a 2020 Evinrude 90. I was disappointed at the demise of Evinrude but think it’s the correct engine. ...

1970 Sakonnet Hydraulic Steering

For a 1970 SAKONNET with an E-TEC 90, the engine dealer estimates a cost addition of $800 for upgrading to hydraulic steering.

Would another steering option be better?

If an Evinrude NAUTILUS 3.5 Color Display were mounted on the vertical plane of the console, the display w...

Thanks for the info. Flymo mentions the physical size of the Mercury. I never thought about that. Good point Flymo. As for the F70, my logic tells me to go for it. My "need for speed" wants the E-TEC 90.
