I had a 429 rampage with a yamaha cv30. Plenty of power. I towed tubes, fished, cruzed. But yeah it was thirsty and noisy and was a shit to start most of the time. Surely a 40hp 4 banger with the right prop would be adequate. Or go for an etec 30hp? Maintenamce on a 2stroke is dead simple and cheap. 4 stroke a bit more in depth for the average dude. My boat was stable as can be and i would carry 4 fat dudes no probs with 30hp of two stroke fury.

On my Seafarer venus, i had to use bigger screws drilled into fresh holes. No problems now.

Thats a ripper day! Top effort. What was your most successful rig?

smoke level and smell is same as brp xd50. I can not pick any fifference in performance between the two. I even checked a plug and found the same carbon build up as xd50. At $25 for 3.8L thats pretty good.

At one point i tried running caltex vortex 98 and BRP xd100 synthetic two stroke oil. Ran smooth and smoke free. Too expensive tho at a $riddiculous for fuel and $80 for oil.

Which oil do you use? It should idle ok but yes an older tech 2 stroke outboard will have the occassional shudder and cough. A bit of smoke on the muffs is normal. You can see it easier as there is no lake/sea water covering up the smoke.

I guess thats why its the old one. What did you upgrade to?

Compression check- What PSI would be an ideal reading from the cylinders on my 1998 Johnson Oceanrunner 90hp? The motor has 360hrs of normal recreational use.

Pretty sure it is a US import. Synthetic blend.

Hi there, Whitworths is selling 3.8L of Starbrite Super Premium TCW3 2 stroke oil for $25. Does anyone have any experience with this oil? Smokiness, carbon build up etc

These are all great inputs thankyou. How do the DI compare pricewise to the 4 strokes?

Hi Robsrock, yeah the old OMC 90s are up there in cc's for the horse power. V4 vs 3 cylinder for other brands.

This is for a 5m Seafarer Venus. Fairly heavy boat.

Hi there fishraiders, I would like your suggestions for a 1998 90hp Johnson Ocean Runner replacement. The old girl has treated me reasonably well, it has 360hrs on it. But I am considering a repower. I am thinking of going another carbed 2 stroke as I have a feeling the initial purchase and running costs will prob never meet the purchase cost of a new DI or new 4 stroke. What are your thoughts and why? Make model pros and cons. Cheers Please noone suggest parsun
