Thanks. I don't believe there was a 130 looper, either?

Re: Converting a Sea Drive to Conventional Mount

I have a pair of 1987 Sea Drives. Mine are rated at 110 hp. I don't know about the stamp but the motors look like mine except for the color. At least for 1987 the Sea Drives were painted a metalic charcoal grey. The cowls have Sea Drive plastic name plates that are attached to the cowls with a rubberised adhesive and thru the cowl little plastic studs.<br /><br />Here is what mine look like - I just repainted them so what you see is not the original color.<br /><br />

Yes, there is a 130 looper.

Re: Converting a Sea Drive to Conventional Mount

Thanks, SoLittle. You sure did a nice job painting those babies. Did you use a eurathane paint? Does the linkage look the same as yours? The guy who sold the motor repainted it all inside and out, and I think he only keeps one color for the powerhead. :) <br /><br />Thanks again, Dhadley. Is the 130 looper you're referring to the one that came out in the 90's?

Yes, but the crossflow youre looking at isnt one of them.

The linkage looks the same - mine are crossflow bubble backs @ 110 hp per the OMC shop manual - 1987.<br /><br />The paint is Western synthetic enamel.

Hard to say what it is. Is has VRO and Electrical primer which came out around 85-87, and the silencer box looks like one from 85, from 87 or 88 I think they were all plastic. The colour on powerhead changed to black in 87 as I remember on both Evin and Johnsons. You have the early green, belonging down mid 70ties, but heads had no coil towers then. I think your motor was brought together from several.

Assuming an 88 and 89 1.6 litre seadrive are the same, if that is a seadrive there would have had to have been some major modifications to the powerhead. My 89 seadrive has one powerpack located on top of the left upper cylendar. Also the timer base linkage is completely different. Some other things don't exactly look the same and I would think if that powerhead had been repainted you would see the black underneath where there were scratches. Just my non expert opinion tho.

The only difference between a Sea Drive powerhead and an outboard powerhead, in the V4 crossflows, was a threaded boss right above the front starboard lower pan mount. Not all V4 crossflow Sea Drives used it but some did.

Re: Converting a Sea Drive to Conventional Mount

Most of the responses are leading me to believe this entire outboard is built across various years and models. No suprise there. :) <br /><br />From studying my '86, 90/110hp service manual, along with the '86 Sea Drive parts catalog, I'm fairly well convinced that this is a 1986 or 1987 Sea Drive powerhead and lower engine cowling (engine pan). How this ended up with a conventional mounting bracket is a mystery to me. Perhaps the powerhead and pan were bolted to a standard midsection, or the sea drive bracket was replaced with a conventional bracket. It's a 25" shaft, so this could be a sea drive unit with the mounting bracket replaced.<br /><br />What gets me is the 1989 model stamp. Think I'll just ignore that for now. :) I suppose it could be a 1989 something or other, with the ignition system being a 1986 or 1987. (I believe they retained the twin powerpack mounting studs for a few years) What worries me the most is what I'll find under the flywheel. I'm worried the clown who built this engine may have used ignition parts which are not compatible with each other. (There have been problems with the engine)<br /><br />I'll find out for sure this winter when I take a closer look at the engine.<br /><br />Many thanks for the replies!

Try to post back here with what you find. There are a few of us Sea Drive folks left.

Re: Converting a Sea Drive to Conventional Mount

SoLittle, great paint job on your motor. What type of paint did you use on them. I was told that certain metal based paints cam cause the aluminum to eat away because the different metal set up electrolsis. Do you have any info on this?<br /><br />Also how did you post these pictures, they are great.

Photos were posted from:<br /><br /> http://photobucket.com/albums/v480/Solittle/ <br /><br />I used a Fuji FinePix 3000 point & shoot digital camera.<br /><br />I do need to learn how to resize the images. These, when posted here, are way to large.<br /><br />I used an automotive paint, Western synthetic enamel. I don't know anything about electrolisis. I sanded all the paint off of the cowls. I degreased and sanded everything else. Then came an automotive primer followed by more sanding. Then one finish coat with the Western - single coat - no clear coat. The blue parts were done with an automotive sprey paint in a can.<br /><br />I am quite pleased with the result.<br /><br />They even run better it seems - - welllll.

Easy peasy japanesy.<br /><br />when you are viewing your album in photobucket one of the options is resizing, they give you a choice of 25% of original, 50% or 75%. Takes all of 10 seconds to do it but be careful - once reduced it can't be enlarged (I keep a full size copy on my harddrive just in case).<br /><br />Aldo
