I have a 1999 Adventure 208, looking for an after market hard top. Live in NJ and suggestions. Also might look to repower and heard that only used four stroke Yamaha that won't submerge the rear scuppers is the F150? The new in line four f200 and F175 would be ok but don't want to spend that much cash. Any one have a six cylinder f200 on 208?

Regarding the power issue, you can easily figure this out yourself - and that would probably be best since you don't know if other people are loading the rest of their equipment the same as you. Plus, what if they have a wet transom/bulkhead and you don't (and vice versa)?

Just subtract the difference in weight between whatever engine you're looking at and your current engine. Then, add that weight onto your engine by placing it on top of the cowling. Partially submerged is no big deal.

Regarding the hardtop, there's plenty of posts on here about that - just do some searching and you'll find lot's of info. For example, Atlantic Towers.

Thanks for the information, already checked with Atlantic Tower just seeing if there are others.

I've seen a few older ones out there with F225s....GW rebalanced the boat and moved some weight forward starting in 2002.

What is your current power?

I have a 2006 208 with a 2006 Yamaha 225 4 stroke and a hardtop . No problem with weight or performance or corrosion in the exhaust port section . Just turned 1100 hours . Had the top custom built and installed by Modlin Aluminum Welding in Farmville, N.C. .Farmville is near Greenville where the Grady Plant is and are used by Grady and Grady owners alike . Great job and a good price . Cheaper than buying it as an option when I purchased the boat .

Thanks for the input, I found a guy who makes custom tops in NJ, he's working on a price for me. NC is a little far.

I don't think you will be happy with a F150 on a 208 with a hardtop. Grady's min hp recommendation for that year 208 with a hardtop was a 2 stroke 175.
The lower HP and extra weight of the F motor will significantly affect performance.
The newer V4 200 would be my choice but if that is not an option, I would look for a used 175 or 200 stroke, perhaps an HPDI model

The new I4 200 will be about 100 lbs heavier....but you are also eliminating your 3 gallon oil tank and rigging which is probably 20 lbs or so...so figure a net difference of 80 lbs.

If you want to see how the boat will float you can either (a) find a kid who weighs about 80 lbs or (b) buy 4 20 lb bags of ice in the grocery store. Either way, put the weight astern and watch the scuppers.

My guess is the 200 I4 will be a good setup - particularly if you are adding a hardtop down the road. I owned a 208 with a 200 OX (44 mph boat) and ran one with a 175 HPDI. You won't be happy with an F150 if you add the additional weight and wind resistance of a hardtop.

Atlantic Towers in Barnegat will sell you a tower in a box. nice looking product that fits a variety of boats.
Pipe Dreams Marine builds custom towers and they are located in South Jersey search "pipedreamsmarine" Talked to the owner at a boat show bought his bent butts rod holders. great product.
ON Rt 47 in Dennisville across from the Wawa Bluewater welding also sells custom half towers.

I love my aftermarket hard top. Really makes the boat bigger and provides great shade. Not cheap to do though either factory or after.

I repowered in 2006 my 1999 208 with a 2006 Mercury Verado 150 when I too was concerned about motor weight and enough torque to get on plane. An I4 200 was not available at that time. Here is what I know. I do not have a hardtop on the boat. Viewing the boat without anyone aboard but with equipment and a full tank of gas, the scuppers are not under water. The boat gets up on plane just fine and has a top speed of 38-40 mph with 2 people on board. Gas mileage is 3.8 to 4.0 mpg. Since the Verado is supercharged, it probably generates more torque at low speed to get on plane than the Yamaha F150. If you are concerned about the added weight of the hardtop, you might want to consider the Verado I4 200, which weighs the same as the I4 150. With either of these engines, you get fly-by-wire ignition and nice SmartCraft gauges.

By the way, Grady added about 300 pounds to the front of the boat to accommodate the heavier 4-stroke engines. The dry weight of our boat without hard top weighs 2650 pounds and the later 208s weigh 2950 pounds. Maybe you could add weigh in the bow storage areas if you have a scupper-underwater issue.

I am taking delivery today of a new 205 with a 200 I4. I did the sea trial yesterday and I have to say I think that this is the perfect motor for the 20 footers. I test ran a 209 with a 150 and felt that it would be slightly underpowered with a good load or bad conditions. I obviously haven't run the 200 enough to give you true performance numbers, but I expect it to cruise around 25 mph at 3500 and closer to 30 mph at 4000, top end should be in the low 40's. Grady puts a 14.25 x 15 prop on the 205 and a 14.25 x 17 on the 208 and 209 with the 200 I4. The fuel burn should be around 4 mpg. BTW both the technician and salesman that accompanied me on the sea trial agreed that the new I4 200 is the best choice for any of the 20 foot GW's.

I recently sold my 1993 208 that was repowered in 2007 with the 200 etec small block motor. Perfect match. Scuppers not under. Excellent power and very fuel efficient. great combination. I didn't have a hard top, but the way that motor performed, the added weight would not have been a problem. I compared notes with a guy who repowered an older 208 (not as old as mine was) with the yami 200 i4. He loved it. He did have a hard top. His performance numbers were a bit better than mine on the top end. His scuppers were fine. I'd be pricing either one of the above motors if I were you.

Thanks for the reply's I'm checking out a few hard tops this coming week, pipe dreams and boat towers, and GW welding, ballpark price with rocket launchers is about 3k. I'm going to check out the F200 inline 4 possibly take a ride to Delaware (no sales tax).

I have had my 205 with the I4 200 for a week now and have put between 5 and 10 hours on it. I had it out in a 2 to 3 foot following sea yesterday and was able to maintain 25 to 30 mph (on the GPS) with no throttle adjustments. Not sure that I could have done that with the 150.
